I hope it helps :)
14 because you count the height and how much the base is from the farthest point left to right and multiply h=2 b=7 therefor 2x7 is 14
You should guess.e.g y=3 x=0 or y=5 x=3.

Answer:
5 seconds
Step-by-step explanation:
Suppose the front parts of the trains meet at point A. Since both are the same length and traveling the same speed, each will pass point A in time ...
time = distance/speed
time = (1/18 mi)/(40 mi/h) = (1/720 h) × (3600 s)/(1 h) = 5 s
That is, the rear part of each train will be at point A 5 seconds after the front part.
The rear parts will pass each other 5 seconds after the front parts meet.
