In step 2, the associative property of addition is used since x is grouped to the last term.
In step 3, the distributive property of multiplication is used since 3 is multiplied to the terms inside the parenthesis. 
In step 4, multiplication is done.
        
             
        
        
        
yes, since a+b > c for all sides
 
        
             
        
        
        
B - (5 x 8) - 3
