So I'm guessing that the x2 is your way of saying 2 is the exponent right? In that case the equation would be 8x^2 + 12x 
Well you would have to pull out the gcf which in this case will be 4x after pulling out the gcf you should get 4x(2x + 3)
        
                    
             
        
        
        
D they all have the same slope. 
        
             
        
        
        
The answer is B.) The horizontal asymptote y = 11.95 represents that the cost per person approaches $11.95 as the number of people increases.
 
        
                    
             
        
        
        
Common difference = 2nd term - first term 
 = -13-(-6)
 = -13+6
 = -7
 
        
                    
             
        
        
        
Answer:
5 and 5/2 + 10 would be 17 and 1/2
2 and 5/2 - 5 would be -1/2
Hope this helps
