7 is in the box i believe!!
        
             
        
        
        
6.34 rounds to 6. 
3.95 rounds to 4. 
So 6+4=10
        
                    
             
        
        
        
Tree A grew slower. 
4.15 is less than 4.2 and Tree A is growing at the “lesser” rate, making it the slower growing tree.
        
                    
             
        
        
        
Yes,you got the correct answer!
To prove x≥-32:

Therefore x≥32.
Hope it helps!
 
        
        
        
First thing to do here is to factor out the common 5x.  When you do that you end up with this: 

.  It's easy enough now to factor the second degree polynomial inside the parenthesis. The 2 numbers that add up to be 2 and multiply to be -3 are x = 1 and x = -3.  But we also have to consider the fact that 5x = 0 and x = 0.  This is a third degree polynomial, after all, so we need to find 3 solutions.  Here they all are:  x = -3, 0, 1
