A square has side length (4x – 2) cm. What is the area of the square?

16x^2 - 16x+4

Step-by-step explanation:

16x^2 - 16x + 4

Step-by-step explanation:

Area (a) = width (w) times length (l)

Because the length and width of a square are the same, the area will be (4x-2) * (4x-2)

You can use FOIL to solve this.

First: 16x^2

Outside: -8x

Inside: -8x

Last: 4

So that's 16x^2) - 8x - 8x + 4.

Combine like terms to get your final

16x^2 - 16x + 4

x+y = 29, 5x + 2y = 100

i'm guessing it was a multiple first option was the correct answer

hello from mrbilldoesmath!

answer:

x - 3

discussion:

x^2 - 9 = (x-3) (x+3)   so

(x^2-9)/ (x + 3) = x-3
