Determine the type of property:

Answer:

1. 15 x (62 + 40} = 15 x {62 + 40} → Reflexive Property

2. (23 + 12) + 13 = 23 + ( 12 + 13) → Associative Property

3. 15 x ( 23 + 4) = 15 x 23 + 15 x 4 → Distributive Property

4. 99 + 10 = 10 + 99 → Commutative Property of Addition

5. ( 8 + 11 ) + 20 = 8 + ( 11 + 20 ) → Associative Property of Addition

6. 25 x ( 23 + 16) = 25 x 23 + 25 x 16 → Distributive Property

7. 2 x ( 9 + 6 ) = 2 x 9 + 2 x 6 → Distributive Property

8. (9 + 26 ) + 86 = 9 + ( 26 + 86) → Associative Property of Addition

9. ( 13 + 79 ) + 56 = 13 + ( 79 + 86) → Associative Property of Addition

10. 29 + 18 = 18 + 29 → Commutative Property of Addition
