Question

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

Answer 1

area of a rectangle = length times width
= (5x +2)(x-4)
can you expand (using FOIL) group like terms to simplify and match with the choices given

Answer 2

did you get the same as C?
