Answer:
proportional
Step-by-step explanation:
all are multiplied by 3
 
        
             
        
        
        
x2 - 12x - 12 = 0
(x - 6)2 - 48 = 0
(x - 6)2 = 48 
Hence, the answer is (B).
 
        
                    
             
        
        
        
The value of x is √8/3 - 2
Step by step explanation:
The given equation is
3(x+2)^2=8
To find x,
(x+2)²= 8/3
By taking square root on both sides
x+2= √8/3
x=√8/3 -2
x= -0.37
Thus the square root for the given value is -0.37
 
        
             
        
        
        
Step-by-step explanation:
In ten minutes she walked 1-0.5=0.5 miles. 
60 minutes/10 minutes=6. So 0.5 miles ×6=3 miles per hour
