The surface area in this equation is 5x4 which is 20
        
                    
             
        
        
        
Answer:
Distributive
Step-by-step explanation:
You distribute the 5 into 3x+18, multiplying it by each part of the equation (each part is separated by one of these signs: +, -, x, or /) to get 15x (from 5 x 3x) plus 60 (from 5 x 18).

Answer:
I can only read the top 2 dimensions:
The one on the left is 32 ft^2, the one on the right is 31 ft^2
Step-by-step explanation:
left top: (8x5)-(2x4) = 32
right top: (8x4)-(1x1) = 31
left low: (10x?)-(4x7) = ?
right low: (8x?)-(2x6) = ?
 
        
             
        
        
        
Answer:
C) 8 ft
Step-by-step explanation:
you use the pythagorean theorem to find the height. 
a² + b² = c²
a = radius
b = height
c = slant height
15² + h² = 17²
h = 8
