Expression 2: 19r + (3r - 2) - 11
To show that Expression 1 is equivalent to Expression 2, we can apply the associative property by grouping like terms together.
Expression 2 can be simplified as follows:
19r + (3r - 2) - 11 = 19r + 3r - 2 - 11
Using the associative property, we can group the terms (19r and 3r) together:
= (19r + 3r) - 2 - 11
Simplifying further:
= 22r - 2 - 11
= 22r - 13
Therefore, Expression 1 (22r - 13) is equivalent to Expression 2 (19r + (3r - 2) - 11) using the associative property.
Use the Associative Property to demonstrate that Expression 1 is equivalent to Expression 2.
Expression 1: 22r−13
Expression 2: 19r+(3r−2)−11
