The answer is 168 logs.
1st row:          15 logs
2nd row:        18 logs
3rd row:         21 logs
(so, each row has 3 more logs)
4th row:         24 logs
5th row:         27 logs
6th row:         30 logs
7th row:         33 logs
The sum of logs from each row is: 15 + 18 + 21 + 24 + 27 + 30 + 33 = 168 logs
        
                    
             
        
        
        
Answer:
It's Parallel 
Step-by-step explanation:
Perpendicular have to intersect  
 
        
             
        
        
        
Following the principle of supplements angles, the angle next to the 101 is 79°. 79+38+c(call the third angle c) = 180
c = 180-117 =63° x is supplemental to c so 180 = x +c 
180=x + 63 
x =117
        
             
        
        
        
It would be choice b.
The domain is the range of x values which in this case is from -5 to 3.
        
                    
             
        
        
        
Answer:
The answer is  351/5. But if you want to simplify it, it would be the same thing
