is it \(-4\sqrt{x+9}=20\) or is it \[-4\sqrt{x}+9=20\]?
the first one
then there is no answer, because the left hand side \(-4\sqrt{x+9}\) is negative, but the right hand side \(20\) is positive

Other answers:

\(\sqrt{a}\) is always greater than or equal to zero, so when you multiply by \(-4\) the term will be less than or equal to zero, and it cannot equal a positive number
so there is no answer?
No, there is no solution like satellite73 says....
yes, there is no solution to this
