Answer:
Common ratio is 3
The three terms are 162, 486, 1458
Step-by-step explanation:
Given: The first 4 terms of a sequence are 
To find: 
A. the common ratio
B. the next 3 values in the geometric sequence
Solution:
Geometric sequence is a sequence in which each of the terms is obtained by multiplying the previous term by a fixed number.
A.

So, the common ratio is 
B.
The next three values are as follows:

 
        
             
        
        
        
Answer: two equations represent the situation are 
y = 3x and y = x + 4
Step-by-step explanation:
The smaller number was represented by x and its values on the x coordinate.
The larger number was represented by y and its values on the y coordinate.
The larger number is equal to 3 times a smaller number. This means that
y = 3x
Also, the sum of the smaller number and 4 is the larger number. This means that 
y = x + 4
 
        
                    
             
        
        
        
Answer:
a(8a-1)(3a+5)
Step-by-step explanation:
24a³ + 37a² – 5a =
a ( 24a²+ 37a -5) =
a( 24a² +40a -3a -5) =
a [8a(3a+5) -1(3a+5) ]=
a(8a-1)(3a+5)
