To apply the Commutative Property, we can rearrange the terms in the expression without changing their values.
Starting with the expression: 8 + 9f - 2 + 6f - 8f - 4 + 12
We can rearrange the terms in any order. Let's group the terms with 'f' together and constants (numbers without 'f') together:
= (8 - 2 - 4) + (9f + 6f - 8f) + 12
Simplifying each group separately:
= 2 + 7f + 12
Combining the constants:
= 14 + 7f
So, the expression equivalent to 8 + 9f - 2 + 6f - 8f - 4 + 12 using the Commutative Property is:
B. 14 + 7f
