2 and 5/8: You would go from the number the fraction is closest to, and then add the fraction itself.
The answer is -110.
This is because -55-55=-110.
You have to put -55-55 because the question is asking for you to multiply -55 twice, which is technically-55-55.
The first 3 are correct but for the last one I’m not sure
The answer is 4x+28 it was pretty simple you just had to add up all the sides
