Not sure what this means plz ? 1. which property is illustrateda. (m+7.3)+4.1=m+(7.3+4.1)2. 12x+4y+0=12x+4y3. (3r)(2s=(2s)(3r)these are the same question plz

Step-by-step explanation:

a.(m+7.3)+4.1=m+(7.3+4.1)  - Associative property of addition

The addition or multiplication of a several

numbers is the same regardless of how the numbers are grouped. The

associative property will always involve 3 or more numbers. The

parenthesis groups the terms that are considered one unit.

2. 12x+4y+0=12x+4y

Additive Identity Property

This means that you can add 0 to any number...  and it keeps its identity!  The number stays the same!

3.

(3r)(2s=(2s)(3r)

Commutative property of multiplication

The commutative property of multiplication states that two numbers can be multiplied in either order.
