It is an octagon. If an internal angle of an octagon is greater than 180°, then it’s called a concave octagon.
Profound social economic changes occurred
The Neolithic revolution was the first agricultural revolution. It was a gradual change from nomadic hunting and gathering communities and bands to agriculture and settlement. This period is described as a "revolution" because it changed the way of life of communities which made the change. It occurred in different prehistoric human societies at different times. Many societies changed 9–7 thousand years ago.
The term refers to the general time period over which these developments took place. It also applies to the changes which took place: the adoption of early farming techniques, crop cultivation, and the domestication of animals. The Neolithic Revolution is important for developments in social organization and technology.
The Neolithic revolution led to living in permanent or semi-permanent settlements. Because of this fewer people led a nomadic lifestyle. To be able to know who the crops grown belonged to, the concept of land ownership was developed. The natural environment was changed, population densities grew, and people ate more vegetable and cereal foods in their diet. Hierarchies developed in society. Grain was stored, and could be traded. Surplus production from good crop yields helped societies survive bad years.
An example of unit 10 study guide circles geometry is solve for x in the diagram attached.
<h3>What is Geometry?</h3>
This is known to be an aspect of mathematics that deals with the study of different sizes, shapes, positions angles etc.
To find x. bring like terms together.
6x + 33+ 45 = 180
6x + 78 = 180
6x = 180- 78
6x=102
x = 102/6
Therefore x = 17
