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) = 7x^2 − 4x + 2. Which of the following shows the area of the rectangle in terms of x? (L + W)(x) = 7x^2 + 2 (L + W)(x) = 7x^2 − 8x + 2 (L ⋅ W)(x) = 28x^3 − 16x^2 + 8x (L ⋅ W)(x) = 28x^3 − 4x + 2

5 months agoArea is length times width \(A=lw\) So, \((4x)(7x^2 − 4x + 2)\)

5 months agoOkay so it would look like this? 28x^3 - 16x + 2

5 months agoClose, for -16x you forgot to add the exponents and then you forgot to multiply 4x and 2

5 months agoso like 28x^3 - 16x^2 + (I thought you couldnt do that because the two doesnt have a x)

5 months agoThat is when adding, you are distributing here, so you're only really just multiplying

5 months agoso it will be 8x?
