The correct answer is 3.5
Two chords AC and BD are intersecting inside the circle. The Intersecting Chord Theorem states that when two chords intersect inside a circle, the products of their segments are equal.
Thus, for the given circle:
(AE) × (EC) = (BE) × (ED)
The lengths of the segments are
AE = 7
EC = 2
BE = 4
ED = ?
To solve for ED, we simply substitute the known values into the equation
A fraction that is equivalent to -3/2 would be -9/6
A great form to prove this is by using a calculator and dividing -9 by 6 this should get you the answer of 1.5!

If you have 9 divers total and each team can only have 4 divers, then logically the US can select 2 teams of 4 from 9 divers.
Yo sup??
Let the length of river D be x
then the lenght of river C will be 200+x
but,
lenght of river C+lenght of river D=5580
x+x+200=5580
2x=5380
x=2690
Therefore lenght of river D is 2690 and that of C is 2890
Hope this helps
