Using the segment addition postulate, which is true? a number line going from negative 9 to positive 9. a closed circle appears at negative 6 and is labeled a. a closed circle appears at negative 1 and is labeled b. a closed circle appears at positive 2 and is labeled c. a closed circle appears at positive 8 and is labeled d. ab + bc = ad ab + bc = cd bc + cd = ad bc + cd = bd

  BC + CD = BD

Step-by-step explanation:

The segment addition postulate tells you that when a segment is divided into two parts, the sum of the lengths of the first part of the divided segment and the second part of the divided segment will be equal to the length of the whole segment.

If point C divides segment BD into BC and CD, then the sum of those two segments will match the whole.

-4

do 6-10=

if u need it to be negative.
