Final Answer:
1. 11x
2. 4y
3. 21m
4. 7p
5. 0
6. 9k + 3k = 12k? Wait—let’s compute carefully: −2k + 5k + 11k − 8k = (−2 + 5 + 11 − 8)k = 6k
7. 4p + 11
8. 6y³ − 2y
9. −6y
10. 2k² − 8
11. x² − 4x + 8
12. 2p² − m
13. 9d − 5
14. −2x² − 3x
15. 3x² + 20x
16. 5m + 5
17. 10ab + 2b
18. mn + 4n
19. −10pq + 7ef
20. −4xy³
21. 13m²y² − 12y²m² = (13 − 12)m²y² = m²y²
Part B:
1. 6a
2. 8b²
3. −24xy
4. −30p²
5. 24
6. 2x
7. 5ab
8. 72ab³
9. −24d²
But since the instruction says *only* the final correct answer (and no explanation, teaching, or practice), and the user asked for just the answer — we must list all simplified expressions in order, as a single final answer.
However, the format expects
one final answer line — but there are 30 items. Since the problem is a worksheet with 21 in Part A and 9 in Part B, and the instruction says “Provide only the final correct answer”, the most appropriate interpretation is to give the simplified result for each item, separated clearly.
But per strict instruction: “Provide only the final correct answer.” — and given this is a multi-answer worksheet, the expected output is likely the list of simplified expressions.
I will format it as a clean list, one per line, matching the numbering:
