Answers

Answer:

7.7u - 5.1v + 14.5w

Step-by-step explanation:

Given length:

Side A = (1.2u+1.8v) centimeters,

Side B = (6.5u+8.7w) centimeters

Side C = (5.8w-6.9v) centimeters

Perimeter of a triangle = side A + side B + side C

= (1.2u+1.8v) + (6.5u+8.7w) + (5.8w-6.9v)

= 1.2u + 1.8v + 6.5u + 8.7w + 5.8w - 6.9v

Collect like terms

= 1.2u + 6.5u + 1.8v - 6.9v + 8.7w + 5.8w

= 7.7u - 5.1v + 14.5w

Therefore, the perimeter of the triangle is 7.7u - 5.1v + 14.5w

the question is 7a + 10 = 2a

Answers

Answer:

a = -2

Step-by-step explanation:

Subtract 10 from both sides:

7a + 10 - 10 = 2a - 10

Simplify:

7a = 2a - 10

Subtract 2a from both sides:

7a - 2a = 2a - 10 - 2a

Simplify:

5a = -10

Divide both sides by 5 and simplify:

a = -2

Answer:

A = -2

Step-by-step explanation:

Subtract 10 from both sides:

7a + 10 = 2a -10

Simplify the expression, 7a = 2a - 10

Subtract 2a from both sides next

7a - 2a = 2a - 10 - 2a

Subtract 7a - 2a

5a = -10

5a / 5 = -10/5

a = -2

Step-by-step explanation:

the coordinates of the image of point F after a reflection across the x-axis is (1,-1).

What is reflection?

In mathematics, a reflection (also spelled reflexion) is a mapping from a Euclidean space to itself that is an isometry with a hyper plane as a set of fixed.

Here, given that,

Triangle EFG has vertices E(-3,1), F(1,1), and G (4,5).

We have to find the coordinates of the image of point F after a reflection across the x-axis.

Now, we know that,

The rule for reflecting over the X axis is to negate the value of the y-coordinate of each point, but leave the x-value the same.

Hence, the coordinates of the image of point F after a reflection across the x-axis is (1,-1).

The simplified form of the expression (2x^2+4−x^3)+(−4x^2+6x^3−2) in standard form is -2x^3 + 2x^2 + 2.

What is an expression?

An expression is a mathematical phrase that can contain numbers, variables, and operators. It represents a value or a calculation, but it is not simplified to a single value.

To simplify the expression (2x^2+4−x^3)+(−4x^2+6x^3−2) in the standard form, we can combine like terms and apply the order of operations.

Step 1: Add and subtract the terms inside the first set of parentheses:

2x^2 + 4 - x^3 + (-4x^2 + 6x^3 - 2)

Step 2: Combine like terms:

-2x^3 + 2x^2 + 4 - 2

Step 3: Rearrange the terms in standard form, which is the form with the variable with the highest exponent first, and the numerical constant last:

-2x^3 + 2x^2 - 2 + 4

Step 4: Combine the constant terms:

-2x^3 + 2x^2 + 2

Hence, The simplified form of the expression (2x^2+4−x^3)+(−4x^2+6x^3−2) in standard form is -2x^3 + 2x^2 + 2.

Write a program that will solve a quadratic equation: ax2 + bx + c = 0. The program must ask the user to enter the values for a, b and c. It should then determine the discriminant of the parabola and based on the discriminant it should display the real roots: Discriminant = b2 - 4ac > 0 means there will be two distinct real roots. Discriminant = b2 - 4ac = 0 means there will be only one real root. Discriminant = b2 - 4ac < 0 means there will be no real roots. Use the if - then else structure in your program to decide the outcome of the program. User must then use the quadratic equation to solve for x: = − ± √ −

Answers

Answer:

x= -b ±√b²- 4ac/2a

Step-by-step explanation:

ax2 + bx + c = 0

Dividing the quadratic equation by a gives

x2 + b/ax + c/a = 0

x2 + b/ax = - c/a

Applying the square formula

(x)^2 + 2(x) (b/2a) + (b/2a)^2= + (b/2a)^2- c/a

(x+b/2a)^2= b²/4a² - c/a

(x+b/2a)^2= b²/4a² - 4ac/4a²

(x+b/2a)^2= b²- 4ac/4a²

Taking square root of both sides gives

(x+b/2a)= ±√b²- 4ac/2a

x= -b/2a±√b²- 4ac/2a

x= -b ±√b²- 4ac/2a

This is called the quadratic formula and it can solve the value for x for the given value of a, b and c for the quadratic equation.

From this it is concluded that

Discriminant = b2 - 4ac > 0 means there will be two distinct real roots. Discriminant = b2 - 4ac = 0 means there will be only one real root. Discriminant = b2 - 4ac < 0 means there will be no real roots.

This is because a square root of a value greater than 0 is possible and gives two values for roots of x.

The square root of a value less than 0 gives a negative number and therefore the roots are an imaginary number.

The square root of a value greater equal to 0 gives a zero leaving behind only one real root.
