Answer:
The answer would be A. 14 units.
Step-by-step explanation:
If AC is 28 units, and AC goes from one corner to the next, and DE is half of AC, that would make DE 14. Pretty much all you would have to do is divide AC in half since DE is half of AC.
the answer is 8:5
14 +3 - 17
6-4 = 2
1 -9 = -8
