The correct answer is California’s entrance as a free state would upset the legislative balance in favor of the North.
When California applied for statehood, there was a balance of voters in Congress made up of two groups: one group who was in favor of the expansion of the institution of slavery and another group against the expansion of slavery.
To keep these groups from fighting, many different compromises were made throughout the 1800's in order to help keep the peace. An example of this would be the Compromise of 1850. In this compromise, California is admitted as a free state. However,the Southern states get a stronger fugitive slave law in return. This fighting over a balance of power between slave states and non slave states was one of the most significant causes of the American Civil War.
In 1960 BCC this happened
If what I’m imagining is correct, the you have a rectangle with two of the sides being the same length they were when it was a square. But the other two are half as much as the original. Because there are two half’s you can add them to make one whole (one original side length). Divide 21 by 3 to find out the side length, because it’s a square they’re all going to be the same. Now you know that the length off all the sides of the square are 7. To find the area just multiply length times width (7x7), and get 49 square inches as the answer
The German submarine attacked on merchant ships off the south coast of Ireland and this action prompted the British Admiralty to warn the Lusitania ship to avoid the area or take simple evasive action such as zigzagging to confuse U-boat submarine plotting the vessel's course.The captain of Lusitania ignored these recommendations and the ship was hit by an exploding torpedo.
The justification given by Germany was that by stating correctly that Lusitania was an enemy ship and that it was carrying munitions.
At the time word would not spread as quickly as it does now, back then they had ships that were powered by sails and were made of wood, which made for longer trips across the sea.
