(8x+32)/4= 2x+8
2x+8=y+7 With y being the length of a side of square b
y=2x+1
Perimeter of square b: 4(2x+1)=8x+4
Or you could just do this:
32-4(7)=4 so Perimeter of b is 8x+4
Take a picture of the problem so it's easier for people to figure out the solution.
6% is less than 1, so it can't be any whole number.
