enter your answer in the box.

1. Option b)

2.  Option b)

3. Associative property

4. Commutative property

5. -43

Step-by-step explanation:

1. We are given the expression:

Now, if we take minus common from the last two terms, then, the expression would be of the form:

Hence, the given expression is equivalent to option b)

2.  We are given the expression:

Now, if we rearrange the terms in the expression, then, the expression would be of the form:

Hence, the given expression is equivalent to option b)

3. The property mentioned here is the associative property.

4. The property mentioned here is the commutative property.
