apply the commutative property to generate an expression equivalent to 8 plus 9f - 2 plus 6f - 8f - 4 plus 12

To apply the commutative property, we can rearrange the terms without changing their values.

The given expression is: 8 + 9f - 2 + 6f - 8f - 4 + 12

We can rearrange the terms as follows:

= (8 + 12) + (9f + 6f - 8f) + (-2 - 4)
= 20 + (9f + 6f - 8f) - 6
= 20 + 7f - 6
= 14 + 7f

Therefore, the expression equivalent to 8 + 9f - 2 + 6f - 8f - 4 + 12 with the commutative property is 14 + 7f.
