Answer:
21%
Step-by-step explanation:
I think this id right but not 100% sure. I made N a random number (5 in my case) then squared it to make it 25. That means M is 25. So if we increase N by 10 percent (.5) it is 5.5 x 5.5 = 30.25. Then i found the difference between the two (5.25) and found the percentage difference (21%). Basically divided 5.25 by 25 and that is the answer. Hope this is right!!!!
