Answer:
Your answeer choices arent exactly the clearest, but check my explanation for my answers.
Step-by-step explanation:
1. -9 and 9
2. 25 and -25
This is pretty simple math but the only way I can explain this is that positive's oppisite is negative. If you have a positive number ( 5 ) and need to find its opposite, you need to find the negative of 5, which is -5. Good luck!
P.S: I'm a 6th grader so be sure to use your common knowledge too.
PP.S: You can trust my 6-7th grade head because I have an 100 in math.
