Ответ:

$9a^3c^6-5c = c*(9a^3c^5 - 5)$

Объяснение:

$(25a^7c^7 - 15a^4c^2 ): (5a^4c) = 5a^3c^6-3c$

$(16a^4c^9 - 8ac^4 ):(4ac^3 ) = 4a^3c^6 - 2c$

$5a^3c^6-3c+4a^3c^6-2c = 9a^3c^6-5c$

B 2. Read the text and match the sentences if they T (true) or F (false).
We need energy to heat our homes, cook and clean for our families and for transport. It allows us to live a comfortable and easy life. However, if we don’t use this energy properly we will soon run out. Luckily, there are things we can all do to help our planet and conserve our resources.
To begin with, much of the energy used at home goes to heating or cooling our homes. A simple way to help conserve energy is by lowering the thermostat by two degrees in the winter and raising it by two in summer. By doing so, you will not only lower your heating bill, but you will also reduce the amount of carbon dioxide that enters the atmosphere.
Another way you can save energy at home is by buying energy-saving appliances. Appliances like washing machines and cookers use a great deal of gas or electricity to work. When shopping for new appliances, look at the energy-saving sticker; they might be a little more expensive to buy, but they help save energy, and in the end will help you save money on your bills.
A lot of energy is used by means of transport too. One of the many ways to achive low energy usage is to leave the car at home and catch the bus or the train to move around the city. Fewer car in the street means less traffic and it will not only help save energy, but it also reduce the amount of air pollution.
In the end, it is up to every individual to take responsibility and charge their daily habits. If everyone does their part, then we can help save energy and our planet’s resources.

Сделать краткий пересказ ( 15 предложений хватит ) на английском.

I'm in the first year at the university, where I'm studying English. My elder sister, Betty, is studying history at the same university. Betty can organise her time wisely, whereas I do not know what order I should do things in. I find it hard to get up on time, and usually I do not get enough sleep. I have to wind two alarm-clocks to make sure I do not oversleep.

My sister, an early riser, is awake by 7 o'clock, refreshed and full of energy. While I'm wandering round the kitchen, fighting the urge to go back to bed, Уравнения химических реакций my sister manages to have a quick shower, make her bed, put on make up, do her hair, eat a full breakfast and set off to the university. It takes me an hour and a half to get ready. I have a hasty bite and rush out ofthe house. Even if I catch a bus at once I still arrive at the university 15 minutes late, which always makes me feel guilty.

My studies keep me busy all day long. I have 14 hours of English a week. I also have lectures and seminars. At lunchtime I meet up with my sister and we have a snack at the university cafe. After classes I make myself go to the library where I spend about six hours a week reading for my seminars.

My sister and I come home tired. I always find excuses to put my homework off. Unlike me, my sister manages to do the housework and get down to homework. I like the idea of going to bed early, but quite often I have to sit up late, brushing up on my grammar and vocabulary, though I feel sleepy. My sister says that keeping late hours ruins one's health. Of course, I agree.

As my sister and I do not get any time off during the week, we try to relax on the weekends. One of my greatest pleasures is to lie in bed and read my favourite books. My sister is a sporty person. To keep herself fit, Betty goes for a run in the park; from time to time she works out in the gym.

I hate staying in, and sometimes on Saturday night my sister takes me out to a concert or a play. Sometimes we go to a party or to a disco. But more often than not I end up catching up on my studies and my sister goes out. I wonder how I manage to spoil my leisure time.

Every Monday when I awaken I think I should start a new life. I honestly think that I must become well-organised and correct my daily routine. I make plans to go to keep-fit classes, to do shopping with my sister, to do the cleaning and to do a hundred other good things. But then I remember that I have to call on my school friend in the evening, and I put off my plans till next Monday. It is always better to start a new life in a week.
