Question

The length of a rectangle is represented by the function L(x) = 5x. The width of that same rectangle is represented by the function W(x) = 2x2 − 4x + 13. Which of the following shows the area of the rectangle in terms of x?

Answer 1

Area of a rectangle is Length*Width. In this case, it would be (5x)(2x^2-4x+13). Use FOIL to distribute and you have your answer.
