It’s 2=x because you have start with 2 then 5
        
             
        
        
        
Answer:
8
Step-by-step explanation:
k + 9 = 17 
subtract 9 from both sides:
k = 8
 
        
                    
             
        
        
        
If that’s meant to be x^2 - 6x - 16
Then factorise to (x+2)(x-8)
So x intercepts are -2 and 8
        
                    
             
        
        
        
the answer is D x= x 5 because it make sense
