Increasing research and development into new forms of renewable energy are most important because a) the price of gasoline is high. b) people like saving the planet. c) current forms of energy are being depleted. d) it is better to keep innovation progressing.

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
