WHY TRAVEL? If you like a change, travelling is the best way to see
different places and meet different people. When you travel,
you can see and learn lots of new things.
First, you must arrange' your trip. There are many travel
agencies which can help you to choose the place and your
means of transport. Agencies buy tickets, book hotels and
do all the paper work for your trip. When you have tickets
for some kind of transport, you are a passenger.
Then you have to pack your suitcase. Take some clothes
and personal things. Don't forget a camera to take pictures
of some interesting sights of a city or beautiful views of
nature. It is always pleasant to look at the photos of some
happy moments of your life!​

The game has two phases. The first is a night, when the Mafia do secret “murder". The second phase is a "day” when Innocents vote to eliminate a one "Mafiosi". The “days” are usually longer than the “nights” because of discussions and voting. The game ends when all the Mafia members are killed or there are more Mafia members than Innocents. The minimum number of players to play is seven (5 Innocents against 2 Mafia). Besides you should have one independent player - lead. He tells the players to open their eyes and then announces who “died” the previous night. The basic version works best with between twelve players. Best of all is sitting in a circle around a table.

log(3x - 11) + log(x - 27) = 3

log[(3x - 11)(x - 27)] = 3

(3x - 11)(x - 27) > 0         <=>  3x^2 - 92x + 297 > 0

1. 3x - 11 > 0 => x > 11/3   => x > 27

  x - 27 > 0 => x > 27

2.  3x - 11 < 0  => x < 11/3

    x - 27 < 0

=>

одз x ∈(-∞; 11/3) & (27; +∞)

т.к. основание не указанно и написано log делаю вывод, что основание 10

3x^2 - 92x + 297 = 1000

3x^2 - 92x - 703 = 0

D = 92^2 + 4*3*703 = 16900 = 130^2

x1 = (92 - 130) / 6 = -19/3      оба икса подходят под одз

x2 = (92 + 130) / 6 = 37
