They are up and down and left and right
        
             
        
        
        
X² +18x = 0
To complete the square we are going to use formula a² +2ab +b² = (a+b)²
x² +2*9*x = 0
x² +2*9x+9² = 9²
(x+9)² = 9²
√(x+9)² = +/-√9²
x+9 = 9, or x+9 = -9
x=0, or x= - 18
 The equation could be solved different way
x² +18x = 0
x(x+18) = 0
x=0 or x+18=0
x=0 or x=-18
        
                    
             
        
        
        
Y=6/8 
Divide 6y by 8 to get Y :) Have a great night 
        
                    
             
        
        
        
10:24 because if you add up the amount of the books no matter what the genre is you get 24.There are 10 mystery books and it asks for the ratio of mystery books to the total of books so it would be 10:24
        
             
        
        
        
The ordered pair (1,5) would be the correct answer.
