Temperatures do not vary much from place to place on the Indian Subcontinent.

T or F?

False, because India ranges from a mountainous climate in the north near China and Pakistan, and a more tropical climate in the south near the Indian Ocean and Shri Lanka

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
