Answer:
Each property is mentioned with the corresponding expression.
Explanation:
Writing the property in front of every expression:
1. Additive Identity: 11+0 = 11
2. Associative Property of Multiplication: x*(y*z) = (x*y)*z
3. Additive Identity: 8+(-8) = 0
4. Commutative property of Addition: 14+20=20+14
5. Multiplicative Inverse: 2*1/2 = 1
6. Multiplicative Identity : 22*1 = 22
7. Associative Property of Addition: (19+12)+8=19+(12+8)
8. Commutative Property of Multiplication: a*9=9*a
9. Distributive Property: 7(4+11) = 7(4)+7(11)
