Label each significant piece of land and explain when and how America secured each part of our nation represented on the map bel
Zolol [24]

Answer: Here's all the land pieces I know

Louisiana Purchase: Sold by Napoleon to the US in 1803

Flordia: The Adam-Onis Treaty seceded Florida the US

CA, NV, UT, AZ: Treaty of Guadalupe Hidalgo ended the Mexican-American war and these territories are called the Mexican cession.

Texas: (kinda complicated) Texas won its own independence and became the Lone Star state. Because of slave issues they did not admit Texas for a number of years. The Mexcian-American war did secure a lot of these lands

Oregon Territory: This land was previously co-ruled by Britsh and the US. They wanted this to end so they divided the land in half at the 49th parallel. President Polk tried to push for more land but was rejected.

Gadsden Purchase: Last purchase of land until Alaska or Hawaii. Bought from the Mexican government to build an easier railroad route (avoid tunning through the Rocky Mountains). This is a small portion of land below New Mexico.

Explain ONE internal effort on the part of a government to lessen devolutionary pressures in a country.
vesna_86 [32]

Answer:

An internal effort by a government to lessen revolutionary pressures in a country could be to moderate government positions, orienting them towards positions closer to those of the revolutionaries. In this way, a change in the government's positions would be evidenced, which would be seen by the revolutionaries as an assignment in favor of them, calming the conflict as it would be perceived as the partial fulfillment of the objective by the revolutionaries.

1. Carol owns Virgil’s Electrical Corporation. She needs an electrician and is placing a nine line classified ad. The cost of an
olchik [2.2K]

Answer:

The cost of 9 line ad is #52

Explanation:

Given

f(x) = 28 --- x \le 3

f(x) = 28 + 4(x - 3) --- x > 3

Required

The cost of a 9 line ad

This means that:

x = 9

To calculate the cost, we make use of:

f(x) = 28 + 4(x - 3) --- x > 3

Because 9 > 3

So, we have:

f(x) = 28 + 4(x - 3)

f(9) = 28 + 4  * (9 - 3)

f(9) = 28 + 4 * 6

f(9) = 28 + 24

f(9) = 52
