15x − 2
9x − 2
15x + 2
9x + 2

Answer 1

Answer: 15x-2 (answer A)

Explanation:

To find the total travel time, we need to add the time it takes to travel in the morning and the time it takes to travel in the evening:

Total travel time = (3x - 10) + (12x + 8)

Simplifying the expression by combining like terms, we get:

Total travel time = 15x - 2

Therefore, the total travel time is 15x - 2. So, the answer is (a) 15x - 2.
