Answer:
A) Yes, 7
Step-by-step explanation:
The given sequence  An = {13, 20, 27, 34, ...}
Here the first term Ao = 13 and difference between the successive terms is (d) = 7
That is  d = 20  - 13
d = 7
It is an arithmetic sequence. d = 7
Answer: Yes, it is arithmetic sequence and common difference (d) = 7
Thank you.

Answer:
Isolate the variable by dividing each side by factors that don't contain the variable.
n=5, -5
 
        
                    
             
        
        
        
P=4s
s=p/4
a=s^2, using s found above
a=p^2/16, we were told that p=40 so
a=40^2/16
a=100 in^2
        
             
        
        
        
Answer:
y=-2x-2
Step-by-step explanation:
y+4=-2(x-1)
y+4=-2x+2
y=-2x+2-4
y=-2x-2
