Answer:
Option B is correct
Step-by-step explanation:
We need to find g(h(f(x)) 
We first find h(f(x))
f(x) = x-3/x
Putting value of f(x) in place of x in h(x) 
h(x) = 2x+1
h(f(x)) = 2(x-3/x) + 1
          = 2(x-3/x) + 1
          = 2x -6 /x +1
          = 2x-6 +x/x
          = 3x-6/x
Now, putting value of h(f(x)) in g(x)
g(x) = x+3
g(h(f(x)))= (3x-6/x) + 3
             = 3x-6/x + 3
             = 3x-6+3x/x
             = 6x-6/x   
So, Option B is correct.
 
        
             
        
        
        
Answer:
z=3
Step-by-step explanation:
4(z+6)-11=25
add 11 to both sides
4(z+6)-11+11=25+11
simplify
4(z+6)=36
divide each side by 4
(4(z+6))/4=36/4
Simplify
z+6=9
subtract 6 from each side
z+6-6=9-6
simplify
z=3
