Answer:
h = 48
because 32 + 3h + 4 = 180
32 + 4 = 36
36 + 3h - 36 = 180 - 36
3h = 144
3h/3 = 144/3
h = 48

______        _____
    18                 1 pound
324 x 1 = 324       324/18= 18 pounds
Cross multiply then divide as above.
        
             
        
        
        
F(g(x)) = x + 1 . Just replace square root of x-2 to x in f(x)
