You have to begin by declaring what g(f(x)) means. It means that wherever you see an x in g(x) you put in f(x).
It will look like this to start with
g(f(x)) = (f(x) + 5) / (f(x) 
Now substitute into this for g(-3)
g(x^2 + 5) = (x^2 + 5 + 5)/(x^2 + 5) It's time to use some numbers.
g(- 3) = ((-3)^2 + 10)/( (-3)^2 +5)
g(-3) = ( 9 + 10 ) / ( 9 + 5)
g(-3) = (19)/14 <<<<<< answer.
C <<<< answer. 
        
             
        
        
        
I hope this is correct. I solved it using the addition elimination method. The answer is s= 2, and r= 5. I hope that was helpful.
        
             
        
        
        
Answer:
Step-by-step explanation:
10m-2/5=9 and 3/5
10m-2/5=9.6 (where 9 and 3/5 is equal to 9.6)
50m-2=48 (i multiplied 10m by 5 and 9.6 by 5)
50m=50 ( i added 2 to both sides)
m=1 ( i divided by 50 to both sides to find m)
 
        
             
        
        
        
Answer:
B. 12.5 feet below the surface of the water
