In order to derive the base of a triangle from its area, you need its height as well.
In fact, if we solve the area formula for the base, we have

So, the base length would be

where h is the height relative to the base you're interested in.
 
        
             
        
        
        
3e-1.5f-.375 is the answer.
        
                    
             
        
        
        
X^2 + 10X + 21
(X + 3)(X + 7)
        
             
        
        
        
7? Is seems that the 4 is being added with +2 when it got bigger so I’m thinking the 5 would be the same thing +2 equals 7..that’s what I’m thinking
        
             
        
        
        
20 dollars, she will earn this because five percent of one hundred is five, times five by four and you get your answer of twenty!
