If the temperature at 6:00 a.m. was -12° and then at 11:00 a.m. the temperature was 0° which of the following shows the temperature change from 6:00 a.m. to 11:00 a.m.

-12
0
12
24

The correct answer is 12.

To calculate the temperature change, you need to subtract the initial temperature at 6:00 a.m. from the temperature at 11:00 a.m.

0 - (-12) = 12

Therefore, the temperature change from 6:00 a.m. to 11:00 a.m. is 12 degrees.
