Split into squares, find area of each and then add them! :)

Let's call the missing side ? as shown in the problem.
Now set up a equation where everything adds up to 28x+11
?+8x+2+8x+2+5x+12=28x+11
?+21x+16=28x+11
?=28x-21x+11-16
?=7x-5
So 7x-5 is the missing side!
Hope it helps :D
If you raise -4 to the power of 2, you will get -4x-4. So (-4)^2 is the answer.
4x + 8(3x-7) = 22x -65 distributive property
4x +24x -56 = 22x -65distributive property
28x -56 = 22x -65 additive property
6x = -9 subtractive property
x = -3/2 division
