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
(L ⋅ W)(x) = 28x3 − 4x + 2

Best ResponseYou've already chosen the best response.0i am thinking area would just be multiplication of the two equations.. \[4x*(7x^{2}4x+2)=28x^{3}16x+8x\]

Best ResponseYou've already chosen the best response.0The area of a rectangle is L x W, that means if we had function L(x) and W(x) we multiply them together to find the area.

Best ResponseYou've already chosen the best response.0Yes. That's why i asked you what is the area of a rectangle, so you can get a sense of what to do with L(x) and W(x). Which is, you multiply.
