The condition that existed in rome around 100 b.c that contributed to the downfall of the republic was : invasions by neighboring city-states
By this time , the Roman already split into separated territories, making it easier to conquer
hope this helps
The heads are part of Olmec civilization of ancient Mesoamerica. The common reason why they made this because of their religious belief.
<u>Explanation:</u>
The Olmecs are famously known for the statues they carved: 20 ton stone heads, quarried and carved to commemorate their rulers. They are the first known civilization in America and the first to have this unique kind of construction.
Like most of the early Mesoamerican cultures, Olmec also believed in three tiers of existence: the physical realm they inhabited, an underworld and a sky realm, home of most of the gods.
Hi, thank you for posting your question here at Brainly.
All you have to do is add all the angles and equate to the total sum of angles for a quadrilateral.
360 = Angle Q + Angle P + Angle R + Angle S
Other relationships/equations are:
Q = 2P
R = 3b-19
S = 3b+10
Then, substituting...
360 = 2P + P + 3b - 19 + 3b + 10
360 = 3P +6b - 9
360 - 3P + 9 = 6b
6b = 369 - 3P
b = (369 - 3P)/6
b = 61.5 - 0.5P
Once you know the value of P, then you can determine the exact value of b.
