Answer :
The property illustrated in Step 4 is the "associative property of addition". which is the correct answer would be an option (A).
What is the Associative Property of Addition?
The associative property of addition is a rule which states that when adding three or more numbers, we can arrange them in any configuration, and the resultant sum is unaffected by how they are arranged.
(a + b) + c = a + (b + c)
The property illustrated in Step 4 is the "associative property of addition". This property states that the order in which we add numbers does not affect the result of the addition.
In Step 4, we use the associative property to rearrange the terms in the expression so that we can more easily apply the distributive property in the next step.
Hence, the correct answer would be option (A).
