To apply the commutative property, we can rearrange the terms in the expression by grouping like terms together.
First, let's group the terms that have the variable f:
(9f + 6f - 8f) + 8 + (-2) - 4 + 12
Combining like terms:
7f + 8 + (-2) - 4 + 12
Simplifying:
7f + 8 - 2 - 4 + 12
Combining like terms:
7f + 14
So, the expression equivalent to 8 + 9f - 2 + 6f - 8f - 4 + 12 using the commutative property is 7f + 14.
