Answer:
Step-by-step explanation:
The slant height of one side of this pyramid is 5, and the base of this side is 4.  Thus, the area of one slant side is (1/2)(5)(4) = 10 units^2.
There are 4 such sides.  Thus, the total slant surface area is 4(10 units^2), or 40 units^2.  
If you also want to include the base area, the total would be
40 units^2 + 16 units^2 = 56 units^2.
 
        
             
        
        
        
Answer:
$40
Step-by-step explanation:
x is the original price of the gift
(10% of x) is the value of the discount
(10% of x) = 10/100 . x = 0.1 x
0.1 x    is the value of the discount
x - (10% of x) is what was paid, after the discount
x - 0.1 x = 0.9 x
0.9 x    is what was paid 
4 children paid $9/each
4 times $9 = $36
$36 is the total amount that was paid by the children
$36 = 0.9 x
$36 / 0.9 = x
x = $36 / 0.9 = 360 / 9 
x = 40

x = 12 , y = 18    (12, 18) is the solution, intersection of the two lines.
