so thats the answer?

agent0smith · Answer

"simplify" means you need to simplify

emsxx3_ · Answer

but the question don't ask to simplify.

agent0smith · Answer

Questions never ask you to simplify. They always expect you to know to do that.

agent0smith · Answer

All you have to do is simplify the -(-7) and 3^2

Hi, 
 the equation of a circle is (x-h)^2 + (y-k)^2 = r^2 .  the question has given you the following information  the center which is: (-7, 5)  also known as the (h,k) of the equation and the radius which is: 3 and r^2 in the question.   

so all you have to do is :  plug in the numbers into the equation: 

(x+7)^2+ (y-5)^2 = 9  is your answer
