find the prime factors of each term in order to find the GCF
answer is pq^2
 
        
             
        
        
        
8n - 7
because from 8n, 7 is subtracted
        
                    
             
        
        
        
Answer:
B. A one-to-one relation between x and y
Step-by-step explanation:
 
        
             
        
        
        
angles in a triangle add up to 180
so x = 180 - ( 70 + 90 ) = 20
this is because the two other angles in the both of the identical triangles are 70 and 90
