So h is 3x 
b is x
3x plus x equal 972 
4x = 972 
243 is base 
243 times 3 is 729
        
             
        
        
        
Answer:
32x - 8
Step-by-step explanation:
A = LW
A = (8x - 2)(4)
A = 32x - 8
 
        
                    
             
        
        
        
Answer:
Hello, The answer is C. 
Step-by-step explanation:
HOPE THIS HELPS :)
 
        
                    
             
        
        
        
Quadratic equation is 

 WHEN 

So, to make this true subtract 7 from each side. 
The equation is now 
7

 - x - 7 = 0 
Values for a, b, and c: a = 7, b = -1, c = -7 
Plug these variables into the quadratic equation. 
 
 Square -1 to get 1 and multiply -4 x 7 x -7 to get 196. 

Multiply 2 x -7 to get -14, the denominator, and add 1 to 196. 
 
 Since 197 is not a square number, and I don't know if you want to leave it in radical form or not, I will just because it's easier to understand. 
Hope this helps!
