Step-by-step explanation:
You are adding two each time
Notice the picture below
x = 1 and y = -1
now... recall your SOH CAH TOA

now.. what's the value for "r" or the radius? well, using the pythagorean theorem
( (r+2) * (2r-9)-(r^2+17r+30) )/(r+2)
none of the parenthetical operations or power operations can be simplified further, so multiplication and division first, left to right:
(2r(r+2) -9(r+2) - r^2 + 17r +30)/(r+2)
(2r^2 + 2r -9r+18 -r^2 +17r +30 )/(r+2)
(r^2 +10r +48)/(r+2)
