Answer 13

The length of a rectangle is represented by the function L(x) = 4x. The width of that same rectangle is represented by the function W(x) = 7x2 − 4x + 2. Which of the following shows the area of the rectangle in terms of x?

(L + W)(x) = 7x2 + 2
(L + W)(x) = 7x2 − 8x + 2
(L ⋅ W)(x) = 28x3 − 16x2 + 8x
