The length of a rectangle is represented by the function l(x) = 2x. the width of that same rectangle is represented by the function w(x) = 8x2 − 4x + 1. which of the following shows the area of the rectangle in terms of x? (l + w)(x) = 8x2 − 2x + 1 (l + w)(x) = 8x2 − 6x + 1 (l ⋅ w)(x) = 16x3 − 4x + 1 (l ⋅ w)(x) = 16x3 − 8x2 + 2x
