Amount of money Ann earned this week = Amount of money earned in 1hour × Number of Hours she worked

Amount of money Ann earned this week = (4x + 3) × (2x - 1)
= (4x + 3) (2x - 1)
{Draw lines like rainbows to let yourself know which numbers to multiply by}
= (4x × 2x) + [4x × (-1)] + (3 × 2x) + [3 × (-1)]
{Always remember to put in the negative signs if the number if negative}
= 6x^2 + (-4x) + 6x + (-3)
= 6x^2 - 4x + 6x - 3
{Simplify}
= 6x^2 + 2x - 3

[This is an essay question from APUSH, PLS help] Analyze how western expansion contributed to growing sectional tensions between
klio [65]

Answer: Louisiana Purchase in 1803

Explanation: • American System of Henry Clay (1816) supported a high tariff to protect American industries and generate revenue for the federal government; continuation of the Bank of the United States; development of a system of internal improvements to tie the nation together, which would be financed by profits from the tariff, the bank, and the sale of western lands.

• Erie Canal: meant to connect East and West

- no improvements made to connect north and south

• Missouri Compromise/Compromise of 1820 (11 slave and 11 free states when Missouri asked to be admitted to the Union as a slave state) was authored by Henry Clay, "the Great Compromiser."

- Maine was admitted as a free state; Missouri, as a slave state; all future states north of 36 '30 with the exception of Missouri, would come into the Union as free states.

• Tariff of Abominations favored the north, but south was very upset

- This lead to Virginia and Kentucky Resolutions and southern states threatened to secede

- money from tariff could have been used to expand west

• Railroads begin to replace canals as the heart of the American transportation system (1830s and forward); most railroads ran east to west, helping to cement the North/West alliance.

• Gag rule was adopted (1836); this informal rule in Congress allowed slavery petitions to the House of Representatives to be automatically tabled, thus putting off divisive debates over the issue of slavery. The use of the gag rule lasted until 1844.

• New parties popping up everywhere against slavery in westward expansion (ex. Liberty Party)

• James K.Polk (Democrat) favored westward expansion.

- "54 40 or fight" (campaign slogan)

• Oregon Treaty (1846) resulted in the British-American boundary being set at the 49th parallel.

- South wanted more land for the expansion of slavery

• Treaty of Guadalupe Hidalgo (1848) confirmed the United States title to Texas and gave the United States the Mexican Cession, which included California; the United States agreed to pay $15 million for the land and assumed a $3,250,000 payment to United States citizens with claims against Mexico.

• Free soil party joined with Free Liberty party after treaty to oppose slavery in new areas

"Re-annexation of Texas and the Reoccupation of Oregon"

• Compromise of 1850 (Henry Clay, "Omnibus Bill"; Stephen Douglas supported Clay's proposed

- Cal. admitted as a free state

- New Mex and Utah pop sovereignty

- Tex. lost land that would have become free land

- stricter fugitive slave law

• Wilmot Proviso that said land from war with Mexico will be free

Thesis: As America started to gain more western land, new parties popped up that wanted to stop the expansion of slavery, while southerners were not in favor of treaties that made new land free because they wanted to get wealth, while south threatened to secede the nation because of their pro slavery views.

aliya0001 [1]

Answer:

Check below for the answer and explanations

Explanation:

State-dependent memory: is the process of remembering things because they happen when you were in a state that is similar to your current state. Before the opening night, James would have gone through series of rehearsals, it will be easy for him to recollect the things he said or did during the rehearsal and apply same in the opening night.

Arousal theory: This theory explains that people tend to have a better performance when they are psychologically motivated. James felt motivated when he saw his psychology teacher in the audience. This motivation will enhance is performance.

Positive reinforcement: James motivated himself by wanting to use the concept learnt in his psychology class to have a positive thought about the surrounding atmosphere. This is a positive reinforcement because James felt motivated after this consideration.

Selective attention: This is the process of focusing only on relevant information or object. James paid more attention to those whose presence can aid his performance. He did not have to set his gaze on every member of the audience.

Imagery: In this context, imagery is the use of mental, imaginary pictures to influence one's thought process. As James is on the stage, there should be a mental picture of when he was taking similar roles during the rehearsals, this will help him perform better.

Social facilitation: The presence of a large audience aids the performance of some people. They tend to perform better in the presence of crowd. James can utilize the advantage of the cheers and the applause he receives from the audience for a better performance.

Sensory adaptation: As James spends more time outside performing, his senses tend to adapt to that atmosphere and the initial fright and timidity will disappear. At this stage, he begins to perform incredibly well.
