The correct pairing of a property of operations and its example is:
2a + 3b = 3b + 2a ; Commutative Property
This is because the Commutative Property states that the order of addition can be changed without affecting the sum.
The other options are incorrect:
- The expression \(2(a+3) = 2a + 6\) refers to the Distributive Property, not the Associative Property.
- The Distributive Property applies when distributing a factor over a sum or difference, while the Associative Property refers to how numbers are grouped in addition or multiplication.
