a) 4a + 6b -7a+3b=(4a - 7a)+(6b +3b)= -3a+9b= -3(a-3b) или 9b- 3a= 3(3b - a)
b) 4p×20y×(-3x)= - 240pyx
в) 3(3а-4в) - (2в-5а)= 9а - 12в - 2в+5а= 14а-14в= 14(а-в)

How modern technologies are used to save lives.

Hello everyone, dear viewers, i pleasure to see you. Today I want to tell you about finding people using a quadcopter and machine learning .

To this day, one of the main problems in our world is the loss of people.
Yes, people continue to go missing around the world - and often people go missing in the wilderness.
They go for a walk in the forest for mushrooms, lose their orientation, and at the same time the opportunity to return to their families and civilization on their own.

There are many ways to find people. The main method is to build a group of people in a line and walk around the perimeter
fields, forests, where the sufferer could disappear. Of course, this method is good, but it also has its drawbacks.

Now technologies are developing, and it is becoming easier to solve such problems: we can send our geolocation,
but more often people disappear in forests where there is no Internet; we can order a helicopter, which is much more efficient, but this way of finding people
very expensive. And finally, we can use drones that quickly fly over the forest, take photos, shoot videos,
by which volunteers can find victims.

I want to tell you the well-known story of finding the Little Girl from Yakutia. She went outside with her puppy but back
did not return home. The girl's parents with a team of helpers were looking for her for two whole weeks, it's good that her dog was with her, who helped
survive and not freeze. It is in such cases that it is best to use drones, because they are much faster.

But to view each photo, a person spends from 30 seconds. How can you speed up the process of searching for a person from an aerial photograph,
made from a drone? Of course, machine learning training comes to mind. After collecting the required number of test photos and marking people on them,
then you can train the neural network to find them on its own. By installing this neural network into the operating system of drones, we can immediately
see the person's location.
