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.

the correct answer is b. negative exponential growth.

step-by-step explanation:

you can tell it's an exponential function because it decreases rapidly then levels out and never touches the x-axis.

it is negative because the y-axis decreases as the x-axis increases.

therefore it is a negative exponential growth graph.
