What is the value of x in the equation 4 (2x + 14) = 0?
9, 7, -7, -9.
Answer:
x = -7
Step-by-step explanation:
First step is to expand the left side of the equation. To do this, multiple 4 by each term on the inside of the paratheses.
4 * 2x = 8x
4 * 14 = 56
This gives you the equation:
8x + 56 = 0
Now, get the x term on one side by itself by subtracting 56 on both sides:
8x = -56
And solve for x by dividing both sides by 8:
x = -7
It is always helpful to rewrite a quadratic equation in standard form as a first step in solving it.
A. FALSE
B. TRUE
Answer:
A
Step-by-step explanation:
Now when I think of solving it, I think of finding the zeros. Now if you start with the form, for example:
[tex](x+3)(x-3)[/tex]
Then you can easily see the zeros are -3 and 3.
But if you start with the standard form:
[tex]ax^2+bx+c=0\\or\\x^2-9[/tex]
It will be harder to find the zeros and you would do the eqation or factor it.
So if your in the factored form don't go to standard to find the zeros.
The given statement is False.
What is a quadratic equation?An equation with highest degree two, is considered as a quadratic equation.
In standard form, the right side of an equation should be 0 and every component on the left side should be 1.
For example, x² = 4; to express this in standard form, move the number 4 to the left side of the equation, resulting in x² - 4 = 0.
If you are asked to find x in this circumstance, there is no need to write the equation in standard form; simply take this same real number of both of the equation's sides to find x.
Hence, it is not always necessary to write the quadratic equation in standard form then solve.

divide Rs 120 between two students so that one gets 4 times as much as the other
Answer:
One gets Rs 24 and the other Rs 96.
Step-by-step explanation:
Number of parts = 1 + 4 = 5
So one student gets 1/5 of 120 and the other gets 4/5 of 120
120 * 1/5 = 24
120 *4/5 = 4*24 = 96.
Answer:
One would get 96 and another would get 24
Step-by-step explanation:
So first lets create an equation from the words where 4x is what one students has and x is what another has :
120 = 4x + x
Lets solve this now!
120 = 5x (divide by 5 on both sides)
24 = x (1st Student)
(Multiply by 4 on both side to get the second student)
96 =4x (2nd Student)

m<SLT=72 degrees
m<ALG=18 degrees
Step-by-step explanation:
(3x) + (4x +12) = 180
x = 24
4x + 12 = 108 = m<FLS
180 - 108 = 72 = m<SLT

The production costs, C, in thousands of dollars, for an
energy drink company to manufacture cans of energy
drink is given by the model C(x) = 50 +3.8x -0.0038x^2,
where x is the number of cans of energy drinks produce
in one day, in thousands. The company wants to keep i
production cost at or below $781.12.
Given that x is an element of a subset of the integers,
which of the following constraints satisfy the domain of
C(x)?
The answer choices are in the picture.
If the company wants to keep its production costs under $781.12 a reasonable domain for the constraint x is -12.9892≤ x ≤ 1012.99.
What are constraints?A constraint is a condition of an optimization problem that should be satisfied the condition.
Let x is an element of a subset of the integers,
C(x) is the production cost, in thousands of dollars
[tex]C(x) = 50 +3.8x -0.0038x^2,[/tex]
This is a vertical parabola open downward (the leading coefficient is negative)
we know that
For the interval [-12.9892, 1012.99] = -12.9892≤ x ≤ 1012.99
The value of C(x) = C(x) < 781.12
That means the production cost is under $781.12
Remember that the variable x (number of tires) cannot be a negative number.
If the company wants to keep its production costs under $175,000 a reasonable domain for the constraint x is -12.9892≤ x ≤ 1012.99

suppose you have a box with 3 blue marbles, 2 red marbles, and 4 yellow parmbles. you are going to pull out one marble, record its color, remove it from the box and draw another marble. what is the probability of pulling out a red marble followed by a blue marble? the multiplication rule says to use P(red) P(blue).
1. Describe the probability of finding a red marble.
2. describe the probability of finding a blue marble.
3. describe the process of finding the probability of finding a red marble followed by a blue marble if the first marble was permanently removed?
4. what effect did removing the first marble from the box have on the problem
5. describe the probability of finding a red marble followed by the blue marble if the first marble is removed?
Answer:
Step-by-step explanation:
Part A
The probability of finding a red marble. P(red) = red / total
Total = red + yellow + blue
Total = 2 + 4 + 3
Total = 9
P(red) = 2/9 = 0.22222
Part B
P(blue) = blue / total
P(blue) = 3/8 = 0.375
This means that the red marble is permanently gone. The total is different. It is eight not nine.
Part C
The probability of red followed by blue is just the answers to A and B multiplied.
P(red) followed by blue = 2/9 * 3/8
P(red) followed by blue = 0.22222 * 3.75
P(red) followed by blue = 0.0833333
If you are confident of your concellation abilities you could do this as
P(red followed by blue) = 2/9 * 3/8 = 1/3 *1/4 = 1/12 = 0.083333....
Part D
Removing the first marble had the affect of reducing the total number of marbles to 8 and the number of reds from 2 downto 1
Part E
The answer here is 1/12.
8. Select the expression that is equivalent to 12/48.
A. 6(8+6)
B. 12(4+1)

For a craft project, you select the four packages of modeling clay and the set of tools shown at the right. If there is a 6% sales tax, what is the total cost?
Answer:
13.727
Step-by-step explanation:
Explanation
Given: You choose the four packages of modeling clay and the set of equipment indicated on the right for a creative project.
To find: the total cost if there is a 6% sales tax.
We will calculate the total cost of each item and then add.
Tip
The total cost formula is used to combine the variable and fixed costs of providing goods to determine a total.
The formula is: Total cost = (Average fixed cost x average variable cost) x Number of units produced.
Step 1
The cost of 4 packets of clay is given by:
4 x $2.79
Step 2
We will calculate the product:
4 x 2.79 = 11.16
Step 3
We will add the cost of 4 packets of clay and a pack of tools to get the total cost without tax:
$(11.16 + 1.79)
Step 4
We will add the numbers:
11.16 + 1.79 = 12.95
Step 5
The 6% tax on the total price is given by:
6% x $12.95
Step 6
We will calculate the sales tax:
6/100 x 12.95 = 0.777
Step 7
We will add the total cost without tax and tax amount to get the total amount paid:
$(12.95 + 0.777)
Step 8
We will add the amounts:
12.95 + 0.777 = 13.727
Step 9

What is the area of triangle BCD to the nearest tenth of a square centimeter? Use special right triangles to help find the height. ( Show your work). Will Only Mark Brainliest if answered correctly and No resharing another students answer from brainly or any other websites or you'll be reported.
Answer:
Area = 21.7 cm² (nearest tenth)
Step-by-step explanation:
A 30-60-90 triangle is a special right triangle. The measures of its sides have a special relationship in that they are in proportion:
shortest leg : longest leg : hypotenuse = 1 : √3 : 2
The side opposite 30° is the shortest legThe side opposite 60° is the longest leg and is √3 times the length of the shorter leg. The side opposite 90° is the hypotenuse and is twice the length of the shorter leg.So we can also write the ratio as [tex]x : x\sqrt{3} : 2x[/tex] where [tex]x[/tex] is the shortest side.
From inspection of the diagram, the shortest side is 5 cm
⇒ BC (height) = 5 × √3 = 5√3 cm
Now we have the height, we can calculate the area.
Area of a triangle = 1/2 x base x height
= 1/2 x 5 x 5√3
= 21.7 cm² (nearest tenth)
i need help on this 6th grade math problem
Answer: x<17.5
Step-by-step explanation:
Subtract from both sides: x+2.5-2.5<20-2.5
Simplify the arithmetic: x<20-2.5
Simplify the arithmetic: x<17.5
Hope it helps!
Answer: B) 12.5
Step-by-step explanation:
Start by isolating x by subtracting 2.5 from both sides
[tex]x+2.5 < 20\\x+2.5-2.5 < 20-2.5\\x < 17.5[/tex]
This reads as "x is less than 17.5"
D can be eliminated because it is greater than 17.5
C can be eliminated because 17.5 can't be less than itself
So the answer must be B since it is less than 17.5 and greater than A
