1/2 because once you simplify and multiply and divide you get your answer
        
             
        
        
        
Step-by-step explanation:
The slope is described by the the initial and final value of one quantity over the difference between the initial and final of the other 
Rate: for points on a Cartesian plane,(x1, y1) and (x2, y2) 
the slope, m= (y2 - y1)/(x2 - x1)
The rate of change on the other hand is mostly refers to how much a quantity is changing with time i.e the rate of change of y from y1 to y2 can be expressed as 
rate = (y2 - y1)/(t2 - t1)...where t1 and t2 are the various time in y1 and y2 respectively...

Step-by-step explanation:
Answer:
25^9 + 5^17=
=2^18 + 5^17
=5^17(5+1)
=5^17×6
=5^16×30  is divisible by 30
