Answer 1

The Commutative Property states that the order of addition or multiplication does not change the result. In other words, for any numbers \( a \) and \( b \):

• \( a + b = b + a \) (Addition)
• \( a \cdot b = b \cdot a \) (Multiplication)

Looking at the provided responses, we can evaluate them to see which correctly demonstrates the Commutative Property:

1. 3x(9y+6)=(3x+9y)⋅6 – This expression does not demonstrate the Commutative Property because it is an equation involving distribution and addition, not simply a rearrangement of terms.

2. 3x⋅9y⋅6=162xy – This expression does not explicitly demonstrate the Commutative Property, but it shows the result of multiplying the terms together, not the rearrangement.

3. 3x⋅9y⋅6=9y+6+3x – This expression does not demonstrate the Commutative Property as it involves addition rather than a rearrangement of the multiplied terms.

4. 3x⋅9y⋅6=9y⋅6⋅3x – This expression demonstrates the Commutative Property for multiplication, as it shows a rearrangement of the order in which the numbers are multiplied.

Thus, the response that correctly demonstrates the Commutative Property is:

3x⋅9y⋅6=9y⋅6⋅3x.
