I think your problem is:
(17 + a)^2 = 2209
What is 47 squared?
How do I figure (17 + a)^ = 2209
I know a = 30, but how do I get the answer?

did you mean (17+a)^2 = 2209 ?
IF so, take √ of both sides
17+a = √2209
17+a = 47
a = 47-17
a = 30
IF so, take √ of both sides
17+a = √2209
17+a = 47
a = 47-17
a = 30
