Answer:
Step-by-step explanation:
THE TRICK HERE IS TO DISTRIBUTE THE MINUS SIGN TO THE SECOND TERM.
(6X+5)-(X-3)=
6X+5-X+3   (REMEMBER A NEGATIVE TIMES A NEGATIVE EQUALS A POSITIVE) 
NOW COMBINE LIKE TERMS.
5X+8 
 
        
                    
             
        
        
        
A^2+b^2=c^2 
35^2+25^2=25^2
So the answer is 25
