Step-by-step explanation:

Note

-×-=+ and -×+=-

(-6).(-6).(-6).z.z

This implies

-6×-6×-6×z×z

(-×-×-)(6×6×6)(z×z)

Note, -×-×- = +×- = -

Then, 6×6×6=216

Also, z×z=z²

Therefore,

(-×-×-)(6×6×6)(z×z)

=-216z² . Answer

Given the diagram below with line DE║ line AC. Find BC.

Karolina [17]

Answer:

13.5

Step-by-step explanation:

In triangle ABC, DE || AC

Therefore by basic proportionality theorem:

$\frac{BD}{DA} = \frac {BE}{EC} \\\\\therefore \frac{4}{8} = \frac {BE}{9} \\\\\therefore \frac{1}{2} = \frac {BE}{9} \\\\\therefore BE = \frac{9}{2} \\\\\therefore BE = 4.5\\\because BC = BE + EC \\\therefore BC = 4.5 + 9\\\huge \red {\boxed {\therefore BC = 13.5}} \\$
