(−15)+(−15)=−30

Answer 1

The correct expression to represent the diver swimming from 15 feet below sea level (which is represented as -15) up to the surface (0 feet) would be:

\[ (-15) + 15 = 0 \]

This means starting at -15 feet and swimming up 15 feet results in a position of 0 feet (the surface level).

So, the answer is:

(−15) + 15 = 0.
