-x -2 I think . 3-(-5)= -2 and 2x -3x = -x
        
             
        
        
        
Answer:
<em>The correct option is:  C)  4x(3y + 7z)</em>
Step-by-step explanation:
Given expression is:   
First we need to find the GCF(Greatest common factor) of  and
 and  and then we will factor out that GCF.
 and then we will factor out that GCF. 

We can see that the common factors are:  
So, the GCF will be:  
Now factoring out  from the given expression, we will get.....
 from the given expression, we will get.....

So, the complete factorization will be:

for 7 & 8 you use the equation 

your points are (3,8) & (9,5)
so you plug the numbers in 
y2= 5 
y1=8
x2=9
x1=3
you subtract them get a fraction and that is your slope 
9 & 10 
use the equation 

plug you numbers in for y1 and x2 m is your slope plug it in and that is your equation
