Imagine you're on the first train. since you're moving away from second train at 70mph, and that train is moving away from you at 80mph, in total that other train for you is moving away at 150mph (as you are stationary inside the train).
if the two trains are moving apart at 150mph, then to be 600 miles apart it will take 600/150 hours, which you can calculate :)
(20+4)x4 multiply 4x20=80 and 4x4=16. Add 80+16 and get 96.
I think that the third side would be 13 inches. My reasons are :
1) An isosceles triangle's two sides that point upward are usually longer than the last side on the bottom.
2) Unless it is a scalene triangle, either two sides or all sides are equal.
Answer:

x=-3</h2>
solution,
Hope this helps...
good luck on your assignment.
Hey there,
For this question, you need to find the lowest common multiple which in this case is 60.
How i got it?
5= 1 x 5
12= 2 square x 3
Since one is common, take 5 x 2 square x 3 which is equal to 60
Hope you get it :))
You can ask me any doubts if you have :))
