No, the answer's not 0. There's no answer.

its multiple choice and thats an option but my teacher says its 0 how did you arrive at no solution

First of all, if you plug in x=0, \(\sqrt{0+1}+5=6 \neq 0\), so it's wrong. I knew that there was no solution because: \[\sqrt{x+1}=-5\\ x+1=25\\ x=24\] but \(\sqrt{24+1}+5=10\), so x=24 also doesn't work. Since the possible solution did not satisfy the problem and we found no other possibility, that means that there are in fact no solutions.
