Answer (4):
a=ub/k because
u=ak/b   (starting equation)
ub=ak    (multiply b to both sides)
a=ub/k   (divide both sides by k)
Answer (6)
x=g+c-y because
g=x-c+y  (starting equation)
x+y=g+c (add c to both sides)
x=g+c-y  (subtract y from both sides)
 
        
             
        
        
        
Answer:
14(26+53)
Step-by-step explanation:
14*26 + 14*53 can be rewritten as 14(26+53).  The value of this expression is 14(79) = 1106.
 
        
                    
             
        
        
        
Answer:
24,192.
Step-by-step explanation:
The first number must be one of 2,3,4,5,6,7,8 or 9. That is 8 possibilities.
The number of permutations of the other 4 numbers is 9P4
= 9! /  (9-4)!
= 3024
Now we multiply by the 8:
3024 * 8
= 24,192.

Answer:
1058.4 in^2
Step-by-step explanation:
Find the surface areas of the rectangular prism and the triangular prisms separately. 
Triangular: S = (1/2)lP+B, where l is slant height, P perimeter, and B base area.
14(4)= 56 perimeter of base
13 slant height
B = 14x14 = 196
put together:
S = (1/2)(13 x 56) + 196
S = 560 in^2
Now the rectangular prism
S = 2lw + 2lh + 2wh, where l is length, h height, w width. (delete the first 2lw since they share one side/they're combined shapes.
S = 2(14x8.9) + 2(14x8.9)
S = 498.4 in^2
Add them together: 498.4 + 560 = 1058.4 in^2
