Ответ:

$x = 0$

Объяснение:

$x ^{2} - 4 - (x ^{2} - x + 4x - 4) = 3x$

$x ^{2} - 4 - (x ^{2} + 3x - 4) = 3x$

$x ^{2} - 4 - x ^{2} - 3x + 4 = 3x$

$- 3x = 3x$

$- 3x - 3x = 0$

$- 6x = 0$

$x = 0$

1) The Mona Lisa, also known as La Giaconda, became world famous after it
was stolen from the Louvre in 1911. The painting was missing for two years
before police traced the theft to Italian painter, Vincenzo Peruggia, who stole
the work to return it to its country of origin. The Louvre Museum in Paris built
a separate room to house the Mona Lisa, giving up to five million visitors a year
the chance to see the painting.
2) The tradition of telling stories with a series of sequential images has been a
part of Japanese culture long before Superman comic strips. The earliest
examples of pre-manga artwork that influenced the development of modern
Japanese comics are commonly attributed to Toba Sojo, an 11th-century
painter-priest with an odd sense of humor. Toba’s animal paintings satirized life
in the Buddhist priesthood by drawing priests as rabbits or monkeys engaged in
silly activities.
3) When the story in which Holmes died was published in a popular magazine
in 1893, the British reading public was outraged. More than 20,000 people
canceled their subscriptions. The demand for Holmes stories was so great that
Conan Doyle brought the great detective back to life by explaining that no one
had actually seen Holmes go down the Reichenbach Falls. The public, glad to
have new tales, bought the explanation.
4) Caviar refers to the salted eggs of the fish species, sturgeon. At the beginning
of the 19th century, the United States was one of the greatest producers of
caviar in the world. Because of overfishing, commercial sturgeon harvesting
was banned. Today, mostly through farm-raised varieties, caviar production has
returned in America. Some American caviar is very high in quality and has
been compared favorably to wild Caspian caviar.
5) T.S. Eliot wrote in his poem, "The Waste Land," that April was the "cruelest
month." He was living in England at the time, and the weather there can be
dreadfully rainy and cold during spring. But from a cook's point of view, April
is anything but cruel. The month brings us some of the freshest, most wonderful
foods. Consider the first ripe strawberries, asparagus, artichokes, tiny peas, and
so much more.
6) When the eruption of Vesuvius started on the morning of 24 August, 79 AD,
it caught the local population completely unprepared. The catastrophic
magnitude of the eruption was connected with the long period of inactivity that
preceded it. The longer the intervals between one eruption and another, the
greater the explosion will be. Luckily, the frequent but low-level activity of Vesuvius in recent centuries has relieved the build-up of pressure in the magma
chamber.
7) Iron Age Britain can only be understood from the archaeological evidence.
There are few spectacular ruins from Iron Age Britain. Unlike in Classical
Greece or Ancient Egypt, in Iron Age Britain there was no construction of
major cities, palaces, temples or pyramids. Rather, it was an essentially rural
world of farms and villages, which had no economic or religious need to build
palaces, cities, major tombs or ceremonial sites.
A) A happy comeback
B) Dangerous when rare
C) Recovery of a masterpiece
D) Back and deep into the past
E) Return of the popularity
F) From Eastern to Western culture
G) They come back in spring
H) Return to the market
