Certainly! Let’s carefully and clearly match the expressions with equal values.
First, let’s clarify which expressions are equivalent to each other.
1. [tex]\(12n - 4 - 4n \cdot 8n + 1 \cdot 3 + 3n + 4 + 2n\)[/tex]
- This simplifies to: [tex]\(-32n^2 + 17n + 3\)[/tex]
2. [tex]\(3n + 5\)[/tex]
- This simplifies to: [tex]\(3n + 5\)[/tex]
3. [tex]\(n + n + n + 5\)[/tex]
- This simplifies to: [tex]\(3n + 5\)[/tex]
4. [tex]\(5 - 10n + 2 + 15n\)[/tex]
- This simplifies to: [tex]\(5n + 7\)[/tex]
5. [tex]\(-4n - 4 + 4n\)[/tex]
- This simplifies to: [tex]\(-4\)[/tex]
6. [tex]\(4 + 4n + 4 + 4n\)[/tex]
- This simplifies to: [tex]\(8n + 8\)[/tex]
7. [tex]\(-8n + 8\)[/tex]
- This simplifies to: [tex]\(8 - 8n\)[/tex]
8. [tex]\(4(2n - 1)\)[/tex]
- This simplifies to: [tex]\(8n - 4\)[/tex]
9. [tex]\(-5n + 7\)[/tex]
- This simplifies to: [tex]\(7 - 5n\)[/tex]
10. [tex]\(4n + 5 + n + 2\)[/tex]
- This simplifies to: [tex]\(5n + 7\)[/tex]
11. [tex]\(2n + 5 + n\)[/tex]
- This simplifies to: [tex]\(3n + 5\)[/tex]
12. [tex]\(8 - n + 9n\)[/tex]
- This simplifies to: [tex]\(8n + 8\)[/tex]
13. [tex]\(3n + 5 + 5n - 1\)[/tex]
- This simplifies to: [tex]\(8n + 4\)[/tex]
Now, match the equal values:
1. [tex]\(12n - 4 - 4n \cdot 8n + 1 \cdot 3 + 3n + 4 + 2n\)[/tex]
- No match with any other expression.
2. [tex]\(3n + 5\)[/tex] [tex]\(\bullet\)[/tex]
- Matches with:
- [tex]\(n + n + n + 5\)[/tex] [tex]\(\bullet\)[/tex]
- [tex]\(2n + 5 + n\)[/tex]
Use Blue lines to connect these.
3. [tex]\(5 - 10n + 2 + 15n\)[/tex]
- Matches with:
- [tex]\(4n + 5 + n + 2\)[/tex]
Use Red lines to connect these.
4. [tex]\(-4n - 4 + 4n\)[/tex]
- No match with any other expression.
5. [tex]\(4 + 4n + 4 + 4n\)[/tex]
- Matches with:
- [tex]\(8 - n + 9n\)[/tex]
Use Green lines to connect these.
6. [tex]\(-8n + 8\)[/tex]
- No match with any other expression.
7. [tex]\(4(2n - 1)\)[/tex] [tex]\(\circ\)[/tex]
- No match with any other expression.
8. [tex]\(-5n + 7\)[/tex]
- No match with any other expression.
9. [tex]\(3n + 5\)[/tex] [tex]\(\bullet\)[/tex]
- Already matched.
10. [tex]\(4n + 5 + n + 2\)[/tex] [tex]\(\circ\)[/tex]
- Matches with:
- [tex]\(5 - 10n + 2 + 15n\)[/tex]
Use Red lines to connect these.
11. [tex]\(2n + 5 + n\)[/tex]
- Already matched.
12. [tex]\(8 - n + 9n\)[/tex]
- Already matched.
13. [tex]\(3n + 5 + 5n - 1\)[/tex]
- No match with any other expression.
So your final matching looks like this using straight lines:
- Blue Line: [tex]\(3n + 5\)[/tex] [tex]\(\bullet\)[/tex] [tex]\(n+n+n+5\)[/tex] and [tex]\(2n+5+n\)[/tex]
- Red Line: [tex]\(5 - 10n + 2 + 15n\)[/tex] → [tex]\(4n + 5 + n + 2\)[/tex]
- Green Line: [tex]\(4 + 4n + 4 + 4n\)[/tex] → [tex]\(8 - n + 9n\)[/tex]
Remember to use different color lines to connect the matching expressions on your paper or diagram to clearly illustrate the equal values connected by straight lines.
