Answer:
Step-by-step explanation:
if they are Pythagorean triples they should check for the theorem
the biggest value 17/8 should be the hypothenuse 
(17/8)² = 1² + (15/8)² ; square the numbers
289/ 64 = 1+ 225/ 64 ; find the common denominator for addition
289/ 64 = 64+ 225/ 64 ; add
289/ 64 = 289 /64 TRUE so they are Pythagorean Triples
 
        
             
        
        
        
6(x+9) is the factored expression.
        
                    
             
        
        
        
Hundredths = 7
rounded off = 8.07
