This is the product of the square of a binomial expression. Therefore, it will have two factors.
Square of a binomial: a² + 2ab + b² = (a+b)²
The process:
9x² + 24x + 16
= (3x)² +2(3x)(4) + (4)²
= (3x + 4)² or (3x+4)(3x+4)
I hope this helps :)
 
        
             
        
        
        
<h3>Solution :</h3>
Distance between first tree and last tree is 140m .
And distance between each tree (d) = 5 m 
let's solve for number of trees (n) : 





hence, total number of trees = 29.
