The rise would have to be 12.
This is because in order to be "Similar" triangles the sides need to be proportionate.
(1/3 = 4/12)
 
        
                    
             
        
        
        
Answer
After 13.15 years the population of both towns will become equal.
Step-by-step explanation:
Population of the city Anville is given by using the compound interest formula  
The formula of compound interest 
A = p( 1+r/n)^n*t
using this we get
P1 = 16000 (1 + ) ^1*t
) ^1*t
Population of the city of Brinker will be 
P2 = 11000( 1  +  ) ^1*t
) ^1*t
now to make equal population in both towns
P1=P2
16000 (1 + ) ^1*t = 11000( 1  +
) ^1*t = 11000( 1  +  ) ^1*t
) ^1*t

t = 13.15 years
 
        
             
        
        
        
2x+8 is equivalent to 4x+3-2x+5
Step-by-step explanation:
4x+3-2x+5
4x+2x+3+5
2x+8

Answer:
Year = 1995 and population = 315
Year = 2015 and population = 715
Step-by-step explanation:
It is given that the population of two different villages is modeled by the given equations:
 
 
The population of both villages are same after x years after 1980 if
 
 
 
Splitting the middle term, we get
 
 
 
 
It means, after 15 or 35 years, the population will same.
For x=15, years is  and population is
 and population is  
 
For x=35, years is  and population is
 and population is  
 .
.
Therefore, population are equation in Year = 1995 and population = 315 or Year = 2015 and population = 715.
