Given:
In triangle ABC, point D is the centroid, and BD = 6.
To find:
The measure of side BE.
Solution:
We know that the centroid divides each median in 2:1.
In the given figure BE is a median and point D is the centroid. It means point D divides the segment BE in 2:1.
Let BD and DE are 2x and x respectively.
We have, BD = 6 units.
Now,
Therefore, the measure of side BE is 9 units.

Answer:
The Answer is A. 1.4 x 10^5
Step-by-step explanation:
Numbers in Scientific notation have the first number between 1 and 9 and then the decimal, followed by the rest of the numbers. Find the power of 10 by moving the decimal one place a time from right to left until the decimal is between the last number and the next to last.
B. is wrong because the number is .32 x 10^3 instead of 3.2 x 10^2
C. is wrong because it is 2 to the 10th power (2^10) instead of a power of 10
D is wrong because the number is 11.2 x 10^1 instead of 1.12 x 10^2
Hope this helps!! Have an Awesome Day!! :-)
