Explanation:

Step1: Identify property of (a + b) + c = a + (b + c)

This is the associative property of addition. It states that the way in which numbers are grouped in an addition operation does not change the sum.

Step2: Identify property of 4+(0)=4

This is the identity property of addition. The number 0 is the additive - identity, meaning that when 0 is added to any number, the number remains unchanged.

Step3: Identify property of 9 + 8=8 + 9

This is the commutative property of addition. It states that changing the order of the addends does not change the sum.

Answer:

1. Associative property of addition
