Will mark brainliest!!

just need help with question 8 please!!!

They may have higher or lower population densities than other countries. Also, some other countries may be oil rich. Population is a big role because the more people that a country has, the more economic growth. Taxes can be  increased to gain more money from the higher population.

Explanation:

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
