I NEED HELP PLEASE, THANKS! :) What two civilizations are regarded as the earliest roots of Europe’s government systems?

I believe it is the Holy Roman Empire was one of them which took place in 950–1200 and Carolingian Empire which took place in 800–888

Explanation:

The Holy Roman Empire was regarded as one of the earliest roots of the European government because they had one of the earliest forms of democracy. I'm not sure about the Carolingian Empire but I think they were significant. I hope this helped

on the whole, dickens has shown the french revolution and its this site might you. good at his job, and the subject matter he chose, 

254.34

step-by-step explanation:

the formula for area of a circle is given by

a = pi * r^2

a = pi * 9^2

a = 81*pi

using 3.14 as an approximation for pi

a = 3.14*81

a = 254.34
