Question 78175: can some one please check this for me?
I had to solve and check
sqrtx%2B4=3
(sqrtx%2B4%29^2=3^2
x+4=9
x=11
check
sqrt11%2B2=3
sqrt9=3
3=3

You can put this solution on YOUR website!
sqrt%28x%2B4%29=3
%28sqrt%28x%2B4%29%29%5E2=3%5E2
x+4=9
x=5
Check:
sqrt%285%2B4%29=3
sqrt%289%29=3
3=3
Since we squared the root, we're only looking for the positive answer.
