You reflect the triangle across the x axis. Are you looking for the points or what it reflects into?
The correct answer is 3x = 42
There would be a total of 42/3 or 14 packages.
So the problem is 40 divided by 3 which is 13.3% with a line over the 3 because it is infinante
If you want the height of the crate it's volume / base area = 48/16 = 3 feet.
