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

Using the commutative property, we can rearrange the terms in any order without changing the value of the expression.

Let's group the terms with the variable "f" together and the constant terms separately:

8 + 9f - 2 + 6f - 8f - 4 + 12

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

= 7f + 14

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