The answer would be n<4 because 4 is greater than n. 
 
        
                    
             
        
        
        
ratio of adults to students can be written as a fraction
adult tickets / student tickets
140/210 can be simplified to 14/21
14/21 can be simplifed to 2/3
 
        
                    
             
        
        
        
Hello from MrBillDoesMath!
Answer:
8(v+3) ( -1/2 (sqrt(14) - 4 v) (4 v + sqrt(14)) )
Discussion:
Given
64v^3 + 192v^2 - 56 v - 168      
Factor 64v^2 from the first two terms. Factor 56 from the last two terms:
64v^2(v+3) - 56(v  + 3)     => factor (v+3) from both terms
(v+3) (64v^2 - 56)             => factor 8 from both terms in the right ()
8(v+3)(8v^2-7)                   => factor 8y^2-7 
8(v+3) ( -1/2 (sqrt(14) - 4 v) (4 v + sqrt(14)) )
Thank you,
MrB
