President kennedy’s response to the construction of the berlin wall

Kennedy declared his support for Berlin but took no action against the USSR

Explanation:

Upon his return home from the Vienna summit with Khrushchev, Kennedy demonstrated his resolve to protect West Berlin by calling up Army Reserve and National Guard units. The Soviets responded on August 13, 1961, by erecting the twenty-seven-mile-long Berlin Wall, which isolated U.S.-supported West Berlin and prevented all movement between the two parts of the city.  Behind the concrete wall, topped with barbed wire, the Communists built minefields and watchtowers manned by soldiers with orders to shoot anyone trying to escape to the West. Never before had a wall been built around a city to keep people from leaving. The Berlin Wall demonstrated the Soviets’ willingness to challenge American resolve in Europe, and it became another intractable barrier to improved relations between East and West.

the first historical instance of china engaging in internationalism was during the han dynasty.[1] at the start of the han dynasty, the huns in the north were attacking the frontiers of han and trying to obtain riches. emperor wu of han wanted to gain an alliance with a country called dayuezhi so the two countries could join together and fight against the huns.[2] to obtain this alliance, emperor wu sent zhang qian to the west to establish economic and cultural connections.[2] history records that during the han dynasty there were four primary avenues of contact between china and europe. they included the northern land route, the central land route, the southern sea route, and the far southern sea route.[1] the most famous of these routes is the central land route, or the classical silk road, comprising a network of roads stretching from northwest china to the ports of syria and the black sea, which passed through the oasis of the turkestans and northern persia.[1] the silk road was significant for chinese emperors because it provided dominance over central asia by developing resources and provided new markets for the export of china's most valuable resources.[1]

answer

explanation

the given equation is

we can rewrite this as:

let

then the equation becomes:

the factors of 8 that sum up to -9 are {-1,-8}

we split the middle term with these factors to obtain,

we factor by grouping to obtain:

apply the zero product property to get:
