How are the following all connected together, as in a timeline of american racial history?
1. the compromise, black codes, fugitive slave
2. amendments 13, 14, 15
3. jim crow laws and segregation

Amendment 13 abolished slavery and involuntary servitude. Amendment 14 granted citizenship to all people born in the US, regardless of race, etc. Amendment 15 guarantees citizens the right to vote, regardless of race, etc. After the Civil War, white Southerners did not want black people to vote or be able to hold a position in office. Black codes and the Jim Crow laws were created to undo what the Northerners intended to do during the Reconstruction era, which was to give the same freedoms, rights to people of color. It would ensure that colored people would still be a cheap labor force, essentially slavery in a slightly different form.  Jim Crow laws were the basis of early segregation between races in the United States. Public places were segregated by “colored” and “whites.” These places included theaters, restrooms, schools, public transportation, and more. However, there were still large groups that were against segregation, white people included.

for this case we have the following equation:

we apply distributive property to the terms within parentheses.

subtracting 2 on both sides of the equation:

no options provided, here,but the answer to this question is often: a historian cites a japanese newspaper article published a year after the end of world war ii in order to draw conclusions about the effect of the war on the japanese economy.
