Was the age of napoleons, 1799-1815 successful or not?

Napoleon was very successful for a variety of reasons. He was greatly admired by his troops and trusted in him completely. This started because he proved to his troops that he was willing to put himself in danger line with them.

hope it helps!

the answer would be the third option, "no, ariel should have added 9^2 and 12^2 and compared that to 15^2."

this is found through the pythagorean theorem, which is a^2 + b^2 = c^2.

this is the correct way of solving the problem:

9^2 + 12^2 = 15^2

81 + 144 = 225

225 = 225
