If it bisect, then using the Line Bisector Theorem, it must be equal.
So x+6=4x-21
get like terms on 1 side
x+6=4x-21
-x. +21
27= 3x
x=9
plug the x in
CD= 9+6
CD=15
Answer:
D. 5290 feet
Step-by-step explanation:
1 mile = 5280 feet
The closest number to 5280 is 5290.
5000, 5350, and 5500.89 are more further away from 5280 than 5290.
The answer is 6ft hope its helps.Have a good day!
Step-by-step explanation:

Note that Quotient of Powers is

So the answer is

The answer is

or

The slope and length of the given sides of the quadrilateral can be
found by using the coordinates of the vertices.
Correct responses:
<h3>Methods used to find the slope and length of a line</h3>
The given coordinates of the vertices are;
K(-7, 0), J(2, -2), I(8, -9), L(-1, -7)
Therefore;
