Find WY=

Answers

Answer:

WY = 12 units.

Step-by-step explanation:

Given the number line

The location of W is at x = -5The location of X is at x = -1The location of Z is at = 4The location of Y is at = 7

The distance between W and Y can be calculated such as:

WY = [Location of Y] - [Location of W]

WY = [7] - [-5]

WY = 7+5

WY = 12

Therefore, WY = 12 units

If m(x) = x2 + 3 and n(x) = 5x + 9, which expression is equivalent to (mn)(x)?
5x3 + 9x2 + 15x + 27
25x2 + 90x + 84
x2 + 5x + 12
5x2 + 24

Answers

Answer:

5x3+9x2+15x+27

Step-by-step explanation:

The expression that is equivalent to (mn)(x) is 5x³ + 9x² + 15x + 27.

Option A is the correct answer.

What is an expression?

An expression contains one or more terms with addition, subtraction, multiplication, and division.

We always combine the like terms in an expression when we simplify.

We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.

Example: so

1 + 3x + 4y = 7 is an expression.com

3 + 4 is an expression.

2 x 4 + 6 x 7 – 9 is an expression.

33 + 77 – 88 is an expression.

We have,

To find the product of m(x) and n(x), we need to multiply the two polynomials term by term:

m(x) = x² + 3

n(x) = 5x + 9

mn(x) = (x² + 3) (5x + 9)

Multiplying the two polynomials using the distributive property.

mn(x) = 5x³ + 9x² + 15x + 27

Thus,

The expression that is equivalent to (mn)(x) is 5x³ + 9x² + 15x + 27.
