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

    i am thinking area would just be multiplication of the two equations.. \[4x*(7x^{2}-4x+2)=28x^{3}-16x+8x\]

    The 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.

    Yes. 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.
