Объяснение:

((2у+1)/(y+3)^2 -(y-2)/(y(y+3))×y(y^2 -9)/(y^2 +6)=(2y^2 +y-y^2 -y+6)/(y(y+3)^2)×y(y-3)(y+3)/(y^2 +6)=(y^2+6)/(y+3) ×(y-3)/(y^2 +6)=(y-3)/(y+3)

1. Read and say what makes London a unique city WHAT IS LONDON? Speaking about London you should remember that it is unlike any other city in the world. It has wide streets but low houses. This city has never been planned and it has many parts which are different from each other. Modern London is really three cities: the City of London, a commercial and trade centre, the City of Westminster (the West End) that can be called the historical centre of London with lots of historical places and famous parks, and the City of Southwark (the East End), where workers live. London stands on the deep river Thames, which runs into the North Sea, so all kinds of ships can come into the port of London. There is so much to see in London that even Londoners can always find new places of interest. They like to say, "When a man is tired of London, he is tired of life." There are nearly 300 places of interest that are worth seeing in London. They range from magnificent National Gallery to Old St Thomas' Operating Theatre, and from ancient Charterhouse to modern Canary Wharf. Among numerous museums, galleries, churches, parks and gardens there are ten top tourist attractions. Everyone who arrives to London for the first time should start with St Paul's Cathedral, Hampton Court, Buckingham Palace (Changing of the Guard), the British Museum, the National Gallery, Madam Tussaud's, the Houses of Parliament, the Tower of London and the Victoria and Albert Museum. The oldest part of London is Lud Hill, where the city originated. About a mile west of it there is Westminster Palace, where the king lived and the Parliament met, and there is also Westminster Abbey, the coronation church. The British Museum is the largest and richest museum in the world. It was founded in 1753 and contains one of the world's richest collections of antiquities. The Egyptian Galleries contain human and animal mummies. Madam Tussaud's Museum is an exhibition of hundreds of life-size wax models of famous people of yesterday and today. Here you can meet Marilyn Monroe, Elton John, Picasso, the Royal Family, the Beatles and many others.
