3( m - 3) + 4 = 3m - 9 + 4 = 3m - 5
Step-by-step explanation:
There are 5280 feet in a mile and 3600 seconds in an hour.
So a truck driving 45 miles an hour would be driving:

I'll leave the picture to you; draw a rectangle and write 2x+4 along the length and 4x along the width. We don't really know the aspect ratio of the rectangle until we know x so any rectangle is fine.
The perimeter is the sum of all four side lengths,
p = (2x + 4) + 4x + (2x + 4) + 4x
Answer: p = 12x + 8
