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.
![2x=6](https://tex.z-dn.net/?f=2x%3D6)
![x=\dfrac{6}{2}](https://tex.z-dn.net/?f=x%3D%5Cdfrac%7B6%7D%7B2%7D)
![x=3](https://tex.z-dn.net/?f=x%3D3)
Now,
![BE=BD+DE](https://tex.z-dn.net/?f=BE%3DBD%2BDE)
![BE=6+x](https://tex.z-dn.net/?f=BE%3D6%2Bx)
![BE=6+3](https://tex.z-dn.net/?f=BE%3D6%2B3)
![BE=9](https://tex.z-dn.net/?f=BE%3D9)
Therefore, the measure of side BE is 9 units.
Take the square root of both sides
remember to take the positive and negative root
2x+5=-7 or
2x+5=7
solve each
2x+5=-7
subtract 5
2x=-12
divide 2
x=-6
2x+5=7
subtract 5
2x=2
divid 2
x=1
x=-6 or 1
Answer:
60
Step-by-step explanation:
Answer:
When multiplying a number by 10, move the decimal to the right. Whenever a number is multiplied by 10, the decimal is shifted to one place in the right.
Like : ![7.36\times10=73.6](https://tex.z-dn.net/?f=7.36%5Ctimes10%3D73.6)
When multiplying a number by 0.1, move the decimal to the left. This means the number is multiplied by
or we can say the number is simply divided by 10.
So, when a number is divided by 10, the decimal is shifted to one place on the left.
Like : ![44.56\times0.1=4.456](https://tex.z-dn.net/?f=44.56%5Ctimes0.1%3D4.456)
or ![\frac{44.56}{10}=4.456](https://tex.z-dn.net/?f=%5Cfrac%7B44.56%7D%7B10%7D%3D4.456)
A = 28000(0.9275)^5
a = 19219
$19,219 is the answer
