What are some of the environmental implications cited by chinese officials that have occurred as a result of the dam project?

The guy Is correct

Explanation:

I just did the assignment using this dudes information in my wording and he is correct :) thanks

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
