Explanation:

In the late 19th century there was massive industrialization in the united states which led to increase in production of goods and services and also increase in labor influx into the country from different parts of Europe.

The increase in production meant that the supply was overwhelming demand hence the need/importance of seeking foreign trades in the 19th century was very important for the economy of the state. The US produced all kinds of goods including luxury and other forms of goods and services due to the abundance of capital and natural resources.

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
