Question

The length of a rectangle is represented by the function L(x) = 2x. The width of that same rectangle is represented by the function W(x) = 8x2 − 4x + 1. Which of the following shows the area of the rectangle in terms of x?

(L + W)(x) = 8x2 − 2x + 1
(L + W)(x) = 8x2 − 6x + 1
(L ⋅ W)(x) = 16x3 − 4x + 1
(L ⋅ W)(x) = 16x3 − 8x2 + 2x

Answer 1

area is length times width

Answer 2

i.e.
\[2x(8x^2-4x+1)\]

Answer 3

want me to do that?

Answer 4

yeah assuming you want one of the answer choices you have to distribute the \(2x\) to see what you get

Answer 5

16x^3-8x^2+2x ??

Answer 6

is that right?

Answer 7

yesh

Answer 8

Thank you :)))
