TRiangles ABE and ACD are similar because BE and CD are parallel.
Therefore CD / BE = AD / AE
8 / BE = 16 / 10
BE = 8*10 / 16 = 5
Also, 16 / 10 = AC / AB = 20 / AB
AB = 10 * 20 / 16 = 12,5
Perimeter of ABE = 5 + 10 + 12.5
= 27.5 units (answer)
The answer is A
since 2x+3(2x)=16
Hence 8x=16
Answer:
the second one, B
Step-by-step explanation:
This is because in both numbers the decimal was moved back one.
Answer:
90
Step-by-step explanation:
Hello, there!
<span>This is already simplified as there are no like terms that can be combined. x^3 is different than x^2, so it can't be combined.
x^3 is different from y^2 so it can't be combined.
And finally, x^2 is different from y^2, so it can't be combined either.

I hope I helped!
