Let's do this: start with f(x) = x -1. Now substitute the label "g(x)" for x:
f(g(x)) = g(x) - 1 and we are told that f(g(x)) equals x + 1.
Thus, g(x) - 1 = x + 1
Adding 1 to both sides, we get
g(x) = x + 2 (answer)
Since a square has four sides you divide 215 by 4 your answer will be 53.75
Each side 53.75 long
