Answer:
94.2
Step-by-step explanation:
Arc length is basically circumference.
Circumference formula: 2πr
All we need is the radius. 
Radius = r
15 x 2 = 30 (diameter)
Then we are going to multiply by pi.
 Arc length = 30π OR 94.2
 
        
             
        
        
        
1) Take 18 and multiply it by 5 = 90 
2) Then subtract 26 = 64
3) Then subtract 18 = 46
4) Then subtract 12 = 34 
5)  Then subtract 8 = 26
 
The answer is 26. 
        
             
        
        
        
Answer:
   D.  difference of squares
Step-by-step explanation:
Both of the terms x^2 and 9 are squares, so their difference is the difference of squares. The factorization of that is a "special form" that can be usefully memorized.
   a^2 -b^2 = (a -b)(a +b)
   x^2 -9 = (x -3)(x +3)
 
        
             
        
        
        
A=7 is what I got since this was a equation problem
