He 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) = 7x^2 - 4x 2. which of the following shows the area of the rectangle in terms of x?

(l w) (x) = 7x^2 2

(l w) (x) = 7x^2 - 8x 2

(l ⋅ w) (x) = 28x^3 - 16x^2 8x

(l ⋅ w) (x) = 28x^3 - 4x 2

Area = length x width

(l ⋅ w) (x) = 4x (7x^2 - 4x + 2) = 28x^3 - 16x^2 + 8x
