Solution:
To find the difference between the high and low temperatures, we can calculate it using the expression given:-2 - (-10)Here we have a double negative between the two numbers, which turns into a positive, so it becomes:-2 + 10When you add these together, you get:8°FHowever, this result is not listed amongst the options provided in the image, suggesting there may be an error in the available choices. In calculating the difference, we should take the absolute value of the difference between the high and low temperature:|-2 - (-10)| = |8| = 8°FSince that option is not available, there may be a typographical error in the question or the answer choices. Please double-check the question and answers or provide additional context if there's another intended method for solving this problem.
