The associative property of addition states that to add three numbers, any two can be added first, followed by adding the sum to the third. Of the statements given, only

demonstrates this property, so it is the correct choice.

The associative property of addition states that you can group, or "associate," additive terms in any order and still get the same answer. Here does just that: whether you add first and then add , or add first and then , as long as you add those three terms you'll get the same answer.

Working left to right use the distributive property by multiplying the 4 to each term in parentheses.

Now, use the associative property to group like terms. Note that cannot be combined because they are not like terms.

Like terms can be combined with addition or subtraction.

The associative property of addition states:

When considering only addition and subtraction, the order of operations does not matter.

The rule for Associative Property of Addition is

Using this rule, the expression can be written as

The Associative Property of Addition says that when we add more than two numbers the grouping of the addends does not change the sum.

The rule for Associative Property of Addition is

Expression given in the question is:

Hence the property is Associative of Addition.
