8x8x8=512 
hope this is  what its asking 
        
                    
             
        
        
        
I think the answer is 3/2 but i am not sure
        
                    
             
        
        
        
400x1.036 then that multiplied by 1.036 and every answer just multiply by that 
        
                    
             
        
        
        
Answer:
Step-by-step explanation:
23x + xy - y + 3y + 5 - 20x + 6xy = 23x - 20x + xy  + 6xy -y + 3y + 5
                                                      = 3x + 7xy + 2y + 5
Errors:1) The combined coefficients of the x terms should be 3x, not 43x
2) The coefficients of the y terms have been multiplied.
3) The constant was left off.
