You can write 2311 and 3912 in the form 
:
Then
Taken modulo 20, the terms containing powers of 20 vanish and you're left with
We further have
so we end up with
and so 
.
###
If instead you're trying to find 
, you can apply Euler's theorem. We can show that 
using the Euclidean algorithm. Then since 
, and 8 divides 3912, we have
To show 2311 and 20 are coprime:
2311 = 115*20 + 11
20 = 1*11 + 9
11 = 1*9 + 2
9 = 4*2 + 1 => gcd(2311, 20) = 1
Answer:
it's C
It is because it's showing another bird so it's similar because it is

Answer:
C)
Step-by-step explanation:
Well, we know for the first polygon that the short side of the rectangle is 3 and for the second polygon the short side is 6, this means that for the second polygon, all sides will be double of the other side. 2 times the long side of the first rectangle is 18, this is why x = 18.
Hope this Helps!!! :)
