Answer:
5h+5
5(h+1)
Step-by-step explanation:
Equivalent expressions are the ones that look different but are the same. As the statement says that mason works h number of hours during the 5 day week and 5 hours on the weekend, you can write the following expression:
5h+5

5(h+1)
According to this, the equivalent expressions are:
5h+5
5(h+1)
The answer I believe is Dependent
