Answer 1

you first have to square each side to get ride of the squareroot sign. so you know what to do from there?

Answer 2

well then. after you square each side you get \[d^{2}-11=5^{2}\] then you have to add eleven to each side so you now have\[d^{2}=36\] lastly you have yo find the square root of each side to cancel out to get the \[d^{2}\] so your final answer is d=6
