Help ! :) Instead of prospering as they expected, immigrants to the United States in the late 19th century most often lived:

A. in squatter villages on the outskirts of cities.

B. in isolated camps run by the government.

C. on farms located on undesirable land.

D. in the poorest
neighborhoods of major cities.

D. in the poorest  neighborhoods of major cities.

Explanation:

Immigrants moved to the United States in large numbers during the 1800s and early 1900s in order to take advantage of the "American dream" that they had heard so much about.

When they reached the shores of America however, what they found was that you need to work really really hard if you came with nothing or little.

When it came to matters of accommodation, they found that the only places they could afford were in the poorest neighborhoods in the city and so they moved in and made these places their own.

the perimeter of a triangle is 69 cm. side a is 5 cm shorter than side b. side c is twice as long as side a. find the length of each side. i need to know how to do it in 2 equations.  

equations:

a = b-5

c = 2a

a + b + c = 69

i think i will need more detail to answer if this is a specific question on a test, but technology advancements are good for many industries, such as medicine or food industries, new technology could us in medicine in ways such as new scanners to tell us more about our bodies or new cures or vaccines for diseases.
