2ab - 3a = a.(2b-3) 
now the same thing
let's say n=1
a.(2b-3) + n.(2b-3) = (2b-3).(a+n)

30 because tener is 6 sides and you do 6 times 5 to get 30
        
                    
             
        
        
        
Answer:
in 13.95 years the senior class will have 100 students. 
Step-by-step explanation:
P(h) = p(0.92)^t (equation for exponential change)
P(h) - population of highschool (or senior class) = 100
p - staring amount = 320
t = time in years
100 = 320(0.92)^t
1/3.2 = .92^t (divide both sides by 320)
log(1/3.2, .92) = t (log base 0.92 of 1/3.2 equals t)
13.9497 = t
