The lengrh of a rectangle is represented by the function L(x) = 5x. The width of that same rectangle is represented by the function W(x) = 2x^2 - 4x + 13. Which of the following shows the area of the rectangle in terms of x?

Explanation:

just multiply the 2 together to get the area

it would just be


(5x) * (2{x}^(2) - 4x + 13)

use the distributive property


10 {x}^(3) - 20 {x}^(2) + 65

unless you want to simplify the answer, this would be the answer

simplified, it would be


5(2{x}^(3) - 4 {x}^(2) + 13)
