Answer:
C
Step-by-step explanation:

 
        
                    
             
        
        
        
6 and 7 because if you solve for r the answer would be r > 6
        
             
        
        
        
Since both the expressions in x are equal to y then they are equal to each other, so
-2x + 3 = 13x - 4
-15x + 3 = -4
-15x = -7 
x = 7/15
and y = -2(7/15) + 3 =  31/15  = 2 1/15
        
                    
             
        
        
        
Answer: -2 73/100
Explanation: keep the -2 and just look at the .73. The .73 is in the hundredths place so you put it over 100.
        
                    
             
        
        
        
Length = 4w + 2
A = length x width
= (4w + 2) . w
= 4w^2 + 2w ft square
