Which of the following was the main reason for the Lewis and Clark expedition to the pacific northwest ?

a) the nootka sound controversy

b) the louisiana purchase

c) the hudson bay company

d) the astorians

i really really really really really really dont know

answer; (d) i believe that the correct answer is americans finally ran out of ammunition;

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

during the hitler era and it caused them to declare war on germany
