Answer:
- For A: -12
- For C: 12
Step-by-step explanation:
For A:
- 3 × 0 = 0
- 3 × 4 = 12
- Put them together: 0 - 12
- 0 - 12 = -12
For C:
- -4 × 0 = 0
- -4 × 3 = -12
- Put them together: 0 - (-12)
- Simplify: 0 + 12
- 0 + 12 = 12
For B and D, I'm not sure how to phrase the answer, but with my work, you should be able to do it. If you can't figure out B and D, I'll edit my answer or explain in the comments. I hope this still helps!
