Question

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

Answer 1

@GIL.ojei

Answer 2

sine area is =W*L

Answer 3

it will be L(X) * W(x)

Answer 4

i.e 4x( 7x2 − 4x + 2)

Answer 5

=28x^3 - 16x^2 +8x

Answer 6

Ohhh okay, that makes so much sense. Thank you soooo much!

Answer 7

you are welcome
