Composite Numbers Explanation:

Composite numbers are numbers that have more than two factors, meaning they can be divided by more than just 1 and themselves. Let's determine if 8, 9, 10, and 12 are composite numbers.

8:
- Factors of 8 are 1, 2, 4, and 8. Since 8 has factors other than 1 and itself, it is a composite number.

9:
- Factors of 9 are 1, 3, and 9. Like 8, 9 has factors other than 1 and itself, making it a composite number.

10:
- Factors of 10 are 1, 2, 5, and 10. Since 10 can be divided by numbers other than 1 and itself, it is a composite number.

12:
- Factors of 12 are 1, 2, 3, 4, 6, and 12. Similar to the previous numbers, 12 has factors other than 1 and itself, classifying it as a composite number.

In conclusion, all the numbers 8, 9, 10, and 12 are composite numbers because they have factors other than 1 and themselves.
