Algebra vocabulary worksheet for students to practice identifying and understanding key terms in algebra.

Final Answer:
1. B
2. D
3. C
4. A
5. E
6. F

7. 3 terms: (m), (4), (2(7m + 6)) — but note: 2(7m + 6) is one term (a product), so the expression has 3 terms: *m*, *4*, and *2(7m + 6)*.
However, if expanded: *m + 4 + 14m + 12* → 4 terms. But as written (not expanded), it's 3 terms.

But standard convention: in *m + 4 + 2(7m + 6)*, the parts separated by + or – are terms. So:
- Term 1: *m*
- Term 2: *4*
- Term 3: *2(7m + 6)*
→ 3 terms
