Answer:
3rd option


Step-by-step explanation:
So we are given the following points:
(1,5)
(2,15)
(3,45)
(4,135)
This is a geometric sequence because there is a common ratio, 3. That is you can keep multiply 3 to a previous y-coordinate to get the next y-coordinate.
The formula for a geometric sequence is 
where  is the first term and r is the common ration.
 is the first term and r is the common ration.
So we have
 .
.
If you want to know the fifth term, just plug in 5:

Simplifying:



 
        
                    
             
        
        
        
 paint is needed to cover an entire wall : 2  
if 1/2 gallon of paint cover 1/4 of a wall => 1 wall = (1/2)/(1/4) =2
 
        
                    
             
        
        
        
The equivalent expression of 25 - 64 are "a), b) and c)"
The given expression is:
25 - 64
To find, the equivalent expressions are:
a) 25 + 40x - 40x - 64
=  25 - 64, is the equivalent expression.
b) 25 + 13x - 13x - 64
=  25 - 64, is the equivalent expression.
c) (5 + 8)(5 - 8)
Using the algebraic identity,
(a + b)(a - b) = 
= 
=  25 - 64, is the equivalent expression.
d) ( + 13)( - 13)
Using the algebraic identity,
(a + b)(a - b) = 
= 
=   - 169, is not a equivalent expression.
e) 
Using the algebraic identity,
,  is not a equivalent expression.
∴ The equivalent expression of 25 - 64 are "a), b) and c)".
 
        
                    
             
        
        
        
The answrr is D i hope this helps
