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? (l ⋅ w)(x) = 10x3 − 4x + 13 (l ⋅ w)(x) = 10x3 − 20x2 + 65x (l + w)(x) = 2x2 + 1x + 13 (l + w)(x) = 2x2 − 9x + 13

For each expression use a property to write an equivalent expression.

If g(x) is an odd function, which function must be an even function?
