To remove the parentheses, you just distribute.
So, it will become 3ax + 3b^2 - 3c +2. I don't think there is any like term in this expression.
3(x + 3y + 2x − y) = 3(3x + 2y)
= 9x + 6y
See if any of these match an answer option.
In i hour it would be
60/3=20
20x24=480
480x24=11520.
11520 is your answer! :)
Hope this helps!!
