All of the above I believe
<span>x^2+8x-20=0
Factor the left side of the equation
</span><span><span>(x−2)</span><span>(x+10)</span></span>=<span>0
</span>
Set the factors to both equal the number 0
<span><span>x−2</span>=<span><span><span>0
and/or
</span>x</span>+10</span></span>=<span>0
</span>x = 2 and/or x = -10
Answer: 1,001 Nights, also known as Thousand and one Nights or Arabian Nights.

Answer:
There are mainly 4 types of volcanoes.
Explanation:
1. Cinder cones: They are a bowl-shaped crater, build from particle or blobs of congealed lava that is ejected from a single gas vent, as the air is broken into small fragments that are solidified and falls as cinders.
2. Composite volcanoes: stratovolcano or composite cone are those that form a steep-sided, symmetrical cone of large dimensions built around by lavas. Some examples are Mount Shasta in California, Mount Hood in Oregon.
3. Lava domes: There internal structure is defined by bulbous masses of lava, that are too vicious.
4. Shield volcanoes: These are built entirely by fluid lava, and flow p[ours in all directions.
A volcano can change its surrounding weather patterns but not the climate of a place as a climatic zone is composed of stable and static atmosphere like that of poles, tropics, and temperate lands, etc.
Not all volcanic eruptions can be predicted successfully as they are also triggered by an earthquake and the active or dominant type of volcano can be identified based on its previous eruption patterns.
Answer:
An analysis of 5,000-year-old genetic material from preserved human remains found in Sweden suggests that people moving from southern to northern Europe spread agriculture across that continent long ago.
In addition to agricultural know-how, the intrepid farmers brought their genes: They interbred with hunter-gatherer communities to create modern humans living in Europe today.
"Genetic variation of today's Europeans was strongly affected by immigrant Stone Age farmers, though a number of hunter-gatherer genes remain," study researcher Anders Götherström, of Uppsala University in Sweden, said in a statement.
The results of this study, to be published in the April 27 issue of the journal Science, match up well with previous archeological evidence of farming in Europe.
