Answer:

DE is 36/5

Step-by-step explanation:

The ratio between ΔAED and ΔBEC can be found by

\frac{AD}{BC} =\frac{8}{10}

\frac{8}{10} can be reduced as \frac{4}{5}

\frac{4}{5} can be written in the ratio form as 4:5

thus ΔAED : ΔBEC

           4     :     5  

⇒ 5×ΔAED=4×ΔBEC.

So to find DE

5×DE=4×CE, CE=9

DE=\frac{4(9)}{5}

DE =\frac{36}{5}

6(3a-2b+c) expand this equation
KonstantinChe [14]

Answer:

18a-12b+6c

Step-by-step explanation:

We have got 6 common in this factor 6(3a-2b+c)

So,in order to expand it we just need to multiply 6 with the everything in the bracket..

6×3a=18a

6×2b=12b

6×c=6c

If we arrange the factor after multiplying,then it stands like this 18a-12b+6c...

Can someone please help me with this!!!!

You can use the similarity approach of these two triangles CBD and CAE

as a result:
\frac{BD}{AE} = \frac{10}{2x} = \frac{CD}{CE} = \frac{3x}{?}

so:
? = 6x^2 / 10 = 0.6 x^2

and the fact of:

"The segment connecting the midpoints of two sides of a triangle is parallel to the third side and equals its half length"

so:BD = 0.5 AE        10 = 0.5 * 2x        >>> x= 10


Back to:
? =0.6 x^2 = 0.6 * 10^2 = 0.6 * 100 = 60



A

Hope that helps
