Question

What is the answer??12=√160-r

Answer 1

The answer is r=16 you have to square everything

Answer 2

The answer to this is r=16. You take both sides and square it, making 160-r, drop like it’s hot, and making 12= 144. From there, you subtract 160 from 144 leaving you with -16 then divide by negative 1 and get 16. R=16.
