Answer:
h(4z)=4+12z / 5+4z
Step-by-step explanation:
The function h is defined by h(x)=4+3x over 5+x
This can be written as 
h(x)=4+3x / 5+x
The value of the function at any time depends on the value of x. x is the independent variable. The variable,x can take any value at any time.
To find h(4z), it means that x is taking the value of 4z.
We will substitute 4z in the place of x in the function. This becomes 
h(4z)=4+3×4z / 5+4z
h(4z)=4+12z / 5+4z

Answer:
C)x^2 - 6x-6
Step-by-step explanation:
 -3(x + 2) + (x – 3)x=
-3x-6+x^2-3x=
x^2 - 6x-6
 
        
                    
             
        
        
        
Here, what you would do is combine like terms. So you get P+2q.
