Answer:
- The value of both expressions when t = 3 is 30
- The value of both expressions when t = 7 is 54
- The expressions are equivalent
Explanation:
Plug in each value of t into the expressions:
6t + 12, when t = 3 equals 30
6t + 12, when t = 7 equals 54
6(t + 2), when t = 3 equals 30
6(t + 2), when t = 7 equals 54
We have the same answers for both expressions, meaning they are equivalent.
