Ok now do this one
if u cant find the answers then search it up :)

1. Three continents
2. I think it was Trajan
3. Mediterranean Sea
4. 509 BC
5. The fertile soil of the Po and Tiber River Valleys allowed Romans to grow a diverse selection of crops, such as olives and grains. This allowed the empire to have a food surplus to feed its population and trade with other societies. The Mediterranean Sea, on which Rome was centrally located, further heightened Romans' ability to trade with other societies, increasing Rome's economic strength as a result.
6. The Alps and Apennine mountain ranges were natural barriers that helped protect Rome from invasions and provided strategic locations during war time. The Alps provided a roadblock that forced invaders to move through narrow passages allowing Romans time to prepare and attack.
7. The Romans build most of their buildings in the hills because it provides protection from an attack happening.

I hope this helped.

The median is 4 because 2 x’s out 9, 3 x’s out 7, 3 x’s out 5, and 4 is the only remaining number.
