What is the difference of the two polynomials 9x2 8x 2x2 3x?

Answers

The difference between the two polynomials (9x²+8x) - (2x²+3x) is:

7x² + 5x.

Polynomial:

A polynomial is a type of algebraic expression where the exponents of all variables must be integers. The exponent of each polynomial variable must be a non-negative integer. A polynomial consists of a constant and a variable, but you cannot divide a polynomial by a variable.

Example: Express the polynomial 5 + 2x + x2 in standard form.

To express the above polynomial in standard form, first check the degree of the polynomial.

The degree of the given polynomial is two. Write an expression involving the degree of the polynomial.

There is a term with variable exponent less than 2, i.e.1, then write it down.

Finally, we write a term with the variable exponent 0 as the constant term.

According to the Question:

Given polynomials is:

(9x²+8x) - (2x²+3x)

First, multiply the negative sign in the second polynomial

i.e., (9x²+8x) - (2x²+3x)

= 9x²+8x - 2x²-3x

Now, evaluate those terms who have same variables

=  9x²  - 2x² +8x-3x

= 7x² + 5x

Hence, the difference between polynomials are: 7x² + 5x.

Is a solution of pair of equations 3x 2y 4 and 2x y 5?

Answers

The solution of this pair of equations is (2, 3).

To solve this pair of equations, we can use the substitution method.

First, we solve the first equation for y:

3x + 2y = 4

2y = 4 - 3x

y = (4 - 3x) / 2

Next, we substitute this expression for y in the second equation:

2x + (4 - 3x) / 2 = 5

2x + 2 - 3x = 10

-x = 8

x = -8

Finally, we substitute this value for x in the expression for y to find the value of y:

y = (4 - 3(-8)) / 2

y = (4 + 24) / 2

y = 28 / 2

y = 14

Therefore, the solution of this pair of equations is (x, y) = (-8, 14).

Is 8 10 15 a right triangle?

Answers

NO, A triangle has sides of lengths 8,10, and 15 is not a right triangle.

A right-angled triangle is a triangle with one of the angles at 90 degrees. A 90-degree angle is called a right angle.

The formula states that in a right triangle:

The square of the hypotenuse is equal to the sum of the square of the base and the square of the altitude.

(Hypotenuse)² = (Base)² + (Altitude)²

c²=a²+b²

The three numbers which satisfy the above formula are the Pythagorean triplets

Properties of right angle:

The largest angle is always 90º and called the hypotenuse which is always the side opposite to the right angle.

The measurements of the sides follow the Pythagoras rule, which cannot have any obtuse angle.

consider c=15 a=10, b=8 substitute in above formula:

Jim received a gift card of $70 for a pizza restaurant the restaurant charges $20 for pizza Ciara received a gift card of $60 for different pizza restaurant the restaurant charges $15 per pizza write an equation to show when the two cards would have the same amount of money left on them

Answers

Answer: 70-20x = 60-15x, where x is the number of pizzas purchased.

Step-by-step explanation:

(TLDR, the solution to the given equation is that the cards will have the same amount of money left on them if both jim and clara buy two pizzas each. feel free read my explanation on how to write equations like this in the future, should you need it.)

so, we know that since jim and clara received $70 and $60 gift cards (respectively), these numbers are called constants, because their original values do not depend on anything (they are given). while these numbers may decrease with the amount of pizzas bought, their original values are fixed.

now, the price for one pizza at jim's pizza restaurant is $20, right? so if you buy 2 pizzas, it'll be $40, 3 pizzas are $60, and so on. but we can actually represent the price of the pizzas as 20x (where x is the number of purchased pizzas, and 20 is the price of one pizza), and this expression works for any number of pizzas you buy. you can also apply this to clara's restaurant, as the total price of the number of pizzas she buys is represented by 15x.

the words charges and left in this problem tells you that you're going to need to subtract from the total amount of money on the gift cards. using the expressions above, the amount of money jim has left on his card can be expressed as 70 (amount of money on the card) MINUS 20x (number of money spent on however many pizzas were bought (x)). likewise, the amount of money left on clara's card after she buys however many pizzas can be represented as 60-15x. you can then set the equations equal to each other and solve for x, which tells you how many pizzas they each need to buy to have the same number of $$ left on their cards.

70-20x = 60-15x

Find the area of the right triangle below.
9m
4m

Answers

Answer:

18 m²

Step-by-step explanation:

The area is the size of a 2-dimensional shape.

Area of a Triangle

The formula for the area of a triangle is [tex]\frac{1}{2}bh[/tex], where b is the base and h is the height.

This formula comes from the fact that a triangle is half of a rectangle. Remember that the area of a rectangle is the base times the height, so a triangle would be half of this.

Solving for Area

The base of the triangle is 9 meters. Then, the height is 4 meters. So, we can plug these values into the formula.

[tex]A=\frac{1}{2}*4m*9m[/tex]

So, A = 18. Then, since meters are being multiplied by each other, the units are meters squared. The final answer is 18 m².

According to a Harris poll, 5% of U.S. adults admitted to having spent money gambling online. If a U.S. adult is selected at random, what is the probability that he or she has never spent any money gambling online

Answers

If a U.S. adult is selected at random, the probability that he or she has never spent any money gambling online is 95.

What is gambling?

Gambling, the betting or staking of something of value, with consciousness of risk and hope of gain, on the outcome of a game, a contest, or an uncertain event whose result may be determined by chance or accident or have an unexpected result by reason of the bettor’s miscalculation.

Given that there was a 5 probability of U.S. adults admitted to having spent money gambling online.

We have to find the probability of a U.S. adult selected randomly that he or she has never spent any money gambling online.

We will assume the probability of the outcome which is known as  P(E) and the probability of the outcome which we need to know as , P(E) since both are the complement of each other. Then we will substitute the value of P(E) in the formula compliment of P(E)= 1-P(E)  so as to obtain compliment of P(E)

Given that there was a 5 probability of U.S. adults admitted to having spent money gambling online, therefore

        P(E) =5

        P(E)= 5/100

               =0.05

The probability of a U.S. adult selected randomly that he or she has never spent any money gambling online will be given as compliment of P(E) , such that

compliment of P(E)= 1-P(E)

                             =0.95

                            = 0.95/100

Answers

Difference between coldest and hottest temperature was greater in march than July.

What is range?

The range is the difference between the highest and lowest values within a set of numbers. To calculate range, subtract the smallest number from the largest number in the set.

Given,

Range of temperature in march = 32°

⇒ difference in temperature in march ΔT = 32°

Range of temperature in July = 8°

⇒ difference in temperature in July Δt  = 8°

Answers

The answers to these partial divisions add up to 30 + 2 = 32, or 192/6. We can calculate the solution by dividing 32 by 100, or 0.32, to get 1.92/6.

What do we mean by an exchange?

The formula for computing 1.92 divided by 6 is 1.92 multiplied by 100, divided by 100, and then multiplied by 1.92. There are 18 tenths and 12 ones in 1.92*100 = 192, which is the result. Due to the fact that both 18 and 12 are multiples of 6, this representation is practical.

Then, we can divide 18 tenths by six to get three tenths (30), and we can divide 12 ones by six to get two ones (2). 30 + 2 = 32, or 192/6, is the result of adding the answers to these partial divisions. To get 1.92/6, divide 32 by 100, which is 0.32, and that gives us the answer.

Solve for x by factoring​

Answers

Answer:

x = 5

Step-by-step explanation:

The area of the rectangle can be found by multiplying length x width:

Total Area = 55:

Length = x + 6

Width = x

Set the equation:

(x)(x + 6) = 55

First, distribute x to all terms within the parenthesis:

(x)(x + 6) = x² + 6x = 55

Next, set the equation equal to 0. Subtract 55 from both sides of the equation:

x² + 6x (-55) = 55 (-55)

x² + 6x - 55 = 0

Then, solve for x. Find factors of x² and -55 that, when combined, will result in 6x:

x² + 6x - 55 = 0

x              11

x            -5

(x + 11)(x - 5) = 0

Then, solve each individual parenthesis:

(x + 11) = 0

x + 11 (-11) = 0 (-11)

x = -11

(x - 5) = 0

x - 5 (+5) = 0 (+5)

x = 5

Note, however, that a side cannot have a negative measurement. Therefore, x = 5 is your only answer.

What is the solution of the equation 8x 3y 5 and 3x 2y 5 answer?

Answers

The solution of the equation is x = 1 and y = 0.

We can solve this equation using the substitution method.

First, subtract 5 from both sides of the equation to isolate the x and y terms:8x - 3y = 0

3x - 2y = 0

Next, divide both sides of the first equation by 8:

x = (3/8)y

Substitute this expression for x into the second equation:

3(3/8)y - 2y = 0

Simplify:

(-13/8)y = 0

Divide both sides by -13/8:

y = 0

Now, substitute y = 0 into the first equation:

8x - 3(0) = 0

Simplify:

8x = 0

Divide both sides by 8:

x = 0

Therefore, the solution of the equation is x = 1 and y = 0.

Answers

The midpoint is the point that is exactly in the middle of two other points.

In geometry, the midpoint of a line segment is a point that is exactly halfway between the two endpoints of the line segment. It is the average of the coordinates of the two endpoints. The midpoint can be calculated by averaging the x-coordinates and y-coordinates of the two endpoints. The formula for the midpoint is ((x1+x2)/2, (y1+y2)/2). The midpoint is also known as the center of the line segment. It can also be useful in finding the equation of the line that passes through the two endpoints of the line segment.

The midpoint is an important concept in geometry and it can be used in different geometric shapes and figures, It can also be used to find the distance between two points, the slope of the line, and the equation of the line that passes through two points.
