Answer:
24 days (or more)
Step-by-step explanation:
I assume you want to figure out how long it will take Tom to write the minimum amount of pages for his school report at that rate?
Since Tom writes 1/2 a page a day and he must write 12 or more pages, then it will take him 2 days to write one page, thus, 24 days to write 12 pages.
Therefore, Tom needs at least 24 days to write his school report.
If you meant -a minus -b, then this equation will then be -7 minus -16
-7-(-16)
-7+16
=9
The answer is true. We know this because 9^2 - 6^2 is 45.
