Final answer:
AB - EF is an illustration of the Distributive property.
Step-by-step explanation:
The given statement is AB CD and CD EF, so AB - EF is an illustration of the Distributive property.
The Distributive property states that when you add two numbers and then subtract another number, you can subtract the second number from each addend separately and then subtract the results. In this case, AB - EF can be written as (AB - CD) - (CD - EF).
Therefore, AB - EF is an example of the Distributive property.
