refection and translation i think
hdjdjsjsj I hope I got it right
I'm not sure if its a dilation if its getting smaller not bigger
 
        
             
        
        
        
X^2+x-30 -- find two numbers that add to one and multiply to -30, which would be 6 and -5. so now you have x^2+6x-5x-30. factor out x and 5 to get x(x+6)-5(x+6). so you get (x+6)*(x-5)
        
                    
             
        
        
        
C since that's the only triangle where A^2+B^2=C^2 (36+64=100).
        
             
        
        
        
Im pretty sure its -125/51
