You can put this solution on YOUR website!

%22f%28x%29%22=sqrt%284-x%29 %22g%28x%29%22=2x%2B3

The way you have it with that (-5) on the end is wrong.  It doesn't
mean that the -5 is multiplied if that's what you thought.

%28f%2Bg%29%28x%29=f%28x%29%2Bg%28x%29=sqrt%284-x%29%2B%282x%2B3%29

Now plug in -5 for x and simplify to find (f+g)(-5).
