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?

A. (L + W)(x) = 7x2 + 2
B. (L + W)(x) = 7x2 -8x + 2
C. (L • W) (x) = 28x3 - 16x+ 8x
D. (L • W)(x) = 28x- 4x + 2
