See: Native Americans and settlers on a land.

Think: The Natives look like they're frightened by something and settlers are the only thing close by.

Wonder: Were the settlers threatening the Natives to move? Or is there a fight going on between them as they were often on bad terms with each other?

Explanation:

Western settlers especially in the 1800s (after the formation of the U.S) were bolder with Native encounters. Because the Natives in all wars involving the U.S patriots chose to side with the French and England and most colonial settlers despised their existence on "their land". Also, the U.S government bought new land from the French & Spanish during this time that was on Native territory, so there were many bloody fights that broke out between western settlers and Native tribespeople.  

the answer is expolration. hope this !

8 - (2a + 7) = a + 40     distribute/multiply - into (2a + 7)

8 - 2a - 7 = a + 40

1 - 2a = a + 40       add 2a on both sides

1 = 3a + 40         subtract 40 on both sides

-39 = 3a       divide 3 on both sides

-13 = a

[proof]

8 - (2a + 7) = a + 40

8 - (2(-13) + 7) = -13 + 40

8 - (-26 + 7) = 27

8 - (-19) = 27

8 + 19 = 27

27 = 27
