#6: Associative Property of Addition
there's no multiplication going on.
To get the answer to question 5, you can use the Identity Property of Multiplication. This property states that any number multiplied by 1 is equal to itself. In the given equation, r * 1 = r, so the answer is r.
For question 6, you can use the Associative Property of Addition. This property states that the grouping of numbers in addition does not affect the sum. In the given equation, (5y + 2) + 14x = 5y + (2 + 14x), so the answer is the Associative Property of Addition.
For question 7, you can use the Associative Property of Multiplication. This property states that the grouping of numbers in multiplication does not affect the product. In the given equation, (m • n) • p = m • (n • p), so the answer is the Associative Property of Multiplication.
