Are these two expressions equivalent? 5 + 7 and 7 + 5

The two expressions 5+7and 7+5 are indeed equivalent. Here’s a detailed breakdown of the options:

A. Yes, because of the identity property

Definition: The identity property states that adding zero to a number does not change its value (e.g., a+0=a).

Not Applicable: This property is not relevant to the expressions 5+7and 7+5, as zero is not involved.

B. Yes, because of the commutative property

Definition: The commutative property states that the order of addition or multiplication can be changed without affecting the result (e.g., a+b=b+a).
