Answer:
27 units squared?
Step-by-step explanation:
I think it is 27, look at the Parallelogram bh formula, base times h equals area. 
 
        
             
        
        
        
Answer:
   y = 6 or 8
Step-by-step explanation:
1. Subtract the constant:
   y^2 -14y = -48
2. Add the square of half the y-coefficient:
   y^2 -14y +49 = -48 +49
Write as a square, if you like:
   (y -7)^2 = 1
3. Take the square root:
   y -7 = ±√1 = ±1
4. Add the opposite of the constant on the left:
   y = 7 ±1  =  6 or 8
The solution is y = 6 or y = 8.
 
        
             
        
        
        
Order of operations
first divide, than add
35/5 = 7
56/7 = 8
7 + 8 = 15
15 is your answer
hope this helps
        
                    
             
        
        
        
Answer:
 23 feet
Step-by-step explanation:
Givens
Volume = pi r^2 h
r = 11
V = 2783 pi
Solution
2783 pi = pi 11^2 * h            Cancel the 2 pi's
2783 = 11^2 h                       Expand 11^2
2783 = 121 * h                       Divide by 121
2783/121 = h
h = 23 feet
