When numbers are written together like that, (other examples: 1/2(2), 4(8), 12(0.5)) It indicates multiplication.

When a negative number is multiplied by a positive number, the result will be negative.

-42 * 3.6 = -151.2

Answer: -151.2

Reasoning: the equation is -42•3.6= ? Even though it’s a negative, you multiply regularly so you can just use the absolute value for when you multiply but when you get your answer, don’t forget to see if you put a negative or if it’s positive- 42
x 3.6
so, when you multiply you get 1512. BUT there’s a decimal. And since there’s only one other number after the decimal, you put the decimal in the answer one space over [in between the 1 & 2] so the answer would be 151.2 but since there are two different signs, and when you have two different signs, you make it negative. So in the end it’s - 151.2 :)

Answer:

sorry for wrong answer

Step-by-step explanation:

Labor unions arose in the nineteenth century as increasing numbers of Americans took jobs in factories, mines, and mills in the growing industrial economy.

The Knights of Labor, founded in 1869, was the first major labor organization in the United States. The Knights organized unskilled and skilled workers, campaigned for an eight hour workday, and aspired to form a cooperative society in which laborers owned the industries in which they worked.

The Knights’ membership collapsed following the 1886 Haymarket Square riot in Chicago. By 1886 the American Federation of Labor (AFL), an alliance of skilled workers’ trade unions, was growing.
