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
The indicated variable for a+3/b=c is a+3/b - c=0. That is the answer i am pretty sure.
Answer:
x² - 6x = -5
x = {1, 5}
Step-by-step explanation:
The square of a number minus six times a number equals negative five.
x² - 6x = -5
Add 5 to both sides
x² - 6x + 5 = 0
Factor
(x - 1)(x - 5) = 0
x = {1, 5}
Answer:
9
Step-by-step explanation:
- so lets use a variable for this so if this (_____) = x
you're equation would be x-11=(-2)
2. Add 11 to both sides
x-11=-2
x-11+11=-2+11
3. x=9
4. 9-11=-2
9-11+11=-2+11
Therefore your answer is 9
it is the chances of something to happen
