What is the length of BE?

A. 3
B. 6
C. 8
D. 9

Answer 1

Hint: BG:GE = 2: 1

Answer 2

??? i'm new to working with centroids, what does that mean? if u don't mind explaining...

Answer 3

if G is the centroid then BG = 2 * GE

Answer 4

ohh, so then does that mean I just add 2 to 6 to get my answer, is that really all u have to do?

Answer 5

no the * means times
length of BG = twice length of GE

Answer 6

ohh, okay... so then what do u do next, do u times the 6 with the 2? im a little confused...

Answer 7

bg = 6 and its twice the size of ge so ge = 3

Answer 8

so, the answer would be 9 right?

Answer 9

yes

Answer 10

because ge + bg = be
3 + 6 = 9
