44 - 16n + 6n - 27 Distributive property
17 - 10n Combine like terms
17 - 10n is our final answer. :)
13 x 45
*585
It estimated to 600 or 550
***
Or try 36 x 13
=468
Close to 500 and 400
The Answer Is 500
Answer:
1 i think
Step-by-step explanation:
You can use the similarity approach of these two triangles CBD and CAE
as a result:

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
AHope that helps
