Answer:
x≤ -7 or x≥ -4  
Step-by-step explanation:
There is a closed circle at -7 and the line goes to the left
x≤ -7  
There is a closed circle at -4 and the line goes to the right
x≥ -4  
Since they both can't be true at the same time it is an or
x≤ -7 or x≥ -4  
 
        
             
        
        
        
Problem 13
10p+10q factors to 10(p+q). If we apply the distributive property, we can distribute the 10 to each term inside (p and q) to get 
10(p+q) = (10 times p)+(10 times q) = 10*p + 10*q = 10p+10q
so we get the original expression again. Here 10 is the GCF of the two terms.
--------------------------------------------------------------
Plug p = 1 and q = 2 into the factored form
10*(p+q) = 10*(1+2) = 10*(3) = 30
As a check, let's plug those p,q values into the original expression
10*p+10*q = 10*1+10*2 = 10+20 = 30
We get the same output of 30
