Write a simplified polynomial expression in standard form to represent the area of the rectangle below. a picture of a rectangle is shown with one side labeled as 5 x plus 2 and another side labeled as x minus 4. a. 5x2 + 18x − 2 b. 5x2 + 13x + 2 c. 5x2 − 18x − 8 d. 5x2 + 13x + 8

The correct option is C.

Step-by-step explanation:

Given information: One side of the rectangle is (5x+2) and another sides of rectangle is (x-4).

The area of rectangle is

Substitute length = (5x+2) and width = (x-4) in the above formula, to find the simplified polynomial expression in standard form to represent the area of the rectangle.

Using distributive property,

On simplification we get

On combining like terms we get

Therefore the correct option is C.

step-by-step explanation:

from this example, we can see that subtracting with integers is the same as adding the opposite. we can solve using a number line or by using the saying "keep, change, change" to us solve. it is important to remember that we can subtract a negative and end up with a larger number than we started with.
