Answer:
✔️4(m + 3)
✔️6m - 2m + 12
Step-by-step explanation:
✔️4(m + 3)
4*m +4*3 (distributive property
4m + 12
Therefore, 4(m + 3) = 4m + 12
✔️6m - 2m + 12
4m + 12
Therefore, 6m - 2m + 12 = 4m + 12
✔️3m - m + 12
2m + 12
Therefore, 3m - m + 12 ≠ 4m + 12
✔️4(m + 12)
4*m + 4*12
4m + 48
Therefore, 4(m + 12) ≠ 4m + 12
