Answer:
8
Step-by-step explanation:
Ok... So this is about as simple as it gets. If you look at BE and ED, you can see the little red lines on them. That means that they are congruent. So if BE=8, then so does ED.
If you need help with anymore problems (or my explanation just doesn't make sense) just let me know.
Those are just repeating equivalent decimals
13/200 is the simplest form
-2 should be distributed to (x-3). so you would get the answer of -2x+6
