It is 30 because u r dividing by 2 every time
Hey there,
Your question states: <span>Find the perimeter of a square whose sides are 7.
When finding the perimeter, we need to multiply each side because it is a square. So 7 times 4 would be 28

I'm not good at math but I think is 3f because you'll be multiplying f(unknown #) by 3 so f(x) would be 3f
