Answer:
480 miles.
Step-by-step explanation:
Let x represent the distance between Maria's house and mountains ans r represent Maria's rate for going trip.
We have been given that there was heavy traffic on the way there, and the trip took 12 hours.


We are also told that hen Maya drove home, there was no traffic and the trip only took 8 hours. Maria's average rate was 20 miles per hour faster on the trip home.

Upon substituting
in equation
, we will get:

Therefore, Maya live 480 miles away from the mountains.
For this case we have the following expression:

Rewriting the expression we have:
1) First we subtract the numbers within the parenthesis:

2) Then, we solve the exponents:

3) Then, multiplication:

4) Finally, the addition of numbers is made:

Answer:
the value of the expression is:
B: 29
