Nash Richard · Answer 1

Sample Response: If both expressions have the same value after substituting and simplifying for x = 6 and x = 2, then they are equivalent. Substitute 6 for each variable, x, in both expressions. Use the order of operations to simplify both expressions. The value of both expressions is 15. Now, substitute 2 for each variable, x, in both expressions. Use the order of operations to simplify both expressions. The value of both expressions is 7. Therefore, the expressions are equivalent.
