Final answer:
The new temperature is 6 Fahrenheit degrees after the temperature rose by 11 degrees from an initial -5 Fahrenheit.
Step-by-step explanation:
The temperature started at -5 Fahrenheit and increased by 11 Fahrenheit degrees. To calculate the new temperature, we add the increase to the starting temperature:
-5°F + 11°F = 6°F
Therefore, the new temperature after the increase is 6 Fahrenheit degrees.
