Rewrite as:
4y=x^2-12x+68
divide by four:
y= x^2/4-3x+17
your answer would be 
(6,8)

Answer:
3,139
Step-by-step explanation:
1,956 + 1,183 = 3,139
 
        
                    
             
        
        
        
First you need the formula for SA of a cylinder: SA = 2(πr^2) + 2πr*h
(area of the top and bottom circles plus the side)
Then plug your values into the equation and rearrange to make h the subject:
1470.3 = 2π13^2 + 2π*13*h
26πh = 1470.3 - 338π
h = (1470.3 - 338π)/26π
   =5.00042...
so h is approximately 5 units :)
