Can someone summarize the influence of gold on the growth of African kingdoms. i need help asap!

the answer is a. since they were a huge producer of cotton and wanted the most money for it.

the american colonists were happy with their vicorty, but the french were mad and the french and indians were not alies, and neither were the french and colonist. i think,

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

d definitly is not
