What is the radius of a circle whose equation is (x 5)2 (y-3)3 42? o 2 unitso 4 unitso 8 units16 unitssave and exitmark this and returnnextsubmit

So what you marked there this 4 units this is true so you are right sure 

hope this will help you 

1. isolate the variable, in this case, d. subtract 35.5 on both sides of the equation.2. 52 subtracted by 35.5 is 16.53. therefore your answer would be d= 16.5this is the basics of pre algebra, isolating variable through adding, subtracting, multiplying, and dividing, if you have any other questions to ask just comment!
