Answer:
P = 12 + 5x
Step-by-step explanation:
P = a + b + c
P = 7 + (x + 4) + (4x + 1)
   = 7 + x + 4 + 4x + 1
   = 12 + 5x
 
        
             
        
        
            
            
                Complete the recursive formula of the geometric sequence -0.56\,,-5.6\,,-56\,,-560,...−0.56,−5.6,−56,−560,...Minus, 0, point, 56

Answer:
The recursive formula is:
Cn = 10C(n-1)
Step-by-step explanation:
Given the geometric sequence. 
-0.56, -5.6, -56, -560, ...
The common ratio is
-5.6/-0.56 = -56/-5.6 = -560/-56 = ... = 10
The recursive formula is easily
Cn = C(n-1) × 10
That is a number is ten times the preceding number. 
 
        
             
        
        
        
Answer:
(-b) is the answer.
Step-by-step explanation:
 2(a-b)-(2a-b)
=2a-2b-2a+b (opening the brackets)
= -b

Answer:
X = 4
Step-by-step explanation:
And then the nearest tenth would be 0
cause all numbers that have 4 round to like 0 or the tenth under it. If it has a five or higher it rounds to 10 or the number above it
