I was born and grown up on the poor land in Duc Tho district, Ha Tinh province. That’s where deeply attaches to me 24 years of life. If anyone who asks me that “What’s the thing your most proud of?” .I will answer that’s my hometown. Duc Tho is the land poor where the people live by rice cultivation, breeding, and fishing. Although the life is very difficult, but the people is very friendly, and studious. In Duc Tho, there is a Tung Anh village where called “Doctor village”. Duc Tho is also the home of Tran Phu Secretary General, and marked many memories of the great leader Ho Chi Minh.

If you come to Duc Tho, you will feel many interesting things, visiting Tran Phu tombstone, La Giang dyke, rowing on La driver, and enjoying the traditional songs. In the evening, they can enjoy a special food which is “mussel rice” – just only eat one time, you will never forget.

Beautiful and unobtrusive! Duc Tho always tries to grow, and to improve the life of people, but keeping the traditional culture.

fuck you

Most of the air pollution results from the burning of fossil fuels, motor vehicles, factories, aircraft and rockets. This can cause acid rain which damages water, soil, and vegetation. Air pollution also contributes to the greenhouse effect which can lead to a series of environmental problems such as global warming, polar ice melting, rise of sea levels and loss of land.

Water pollution is a result of dumping pollutants such as detergents, pesticides, oil, and other chemicals in rivers, which makes the water unclean or contaminated. Rubbish blockages in rivers can also cause pollution.

Soil pollution is a consequence of human activities that alter ecological factors that cross the ecological boundaries of the communities living in the soil. The land environment is home to human beings and most of the shallow creatures, the foundations for civil, industrial and cultural constructions. Land is a precious resource, people use land resources for agricultural production to ensure food supply for people. But with the pace of population growth and the pace of industrial development and urbanization, the area of ​​arable land is shrinking and land quality deteriorates, the average land area head drops. Parularly in Vietnam, the actual depletion of land resources is very worrying and serious.  What do we need to do to protect the environment? That is the question that every one of us needs to answer. In my opinion, protecting the environment is the responsibility of the whole community. Everyone must have a sense of protection. The green, clean, beautiful environment will make our lives better. From the house to the alley, from the alley to the school etc. The place is also clean and airy, many trees, air will be fresh, health will be guaranteed. That everyone wants. At present, I see my class, our school where the concentration of people, not very clean, garbage also lunged, trees are still less. On the street, there are public trash but few people put garbage in the bin, you do not throw it, making the street scene is not beautiful. To protect the environment, I feel we must always have a sense of environmental protection in parular: Do not throw garbage indiscriminately, do not discharge dirty water into ponds, do house cleaning, alleys, schools, not breaking flowers ... and propaganda for people always have common sense and responsibility for environmental protection.

giúp mk water or air thôi nhá bn, 

a) | x+5|+3=7

|x+5|=4

=> x+5=4

Hoặc x+5=-4

=>x thuộc { -1 ; -9}

Vậy x thuộc { -1 ; -9}

b) 25 - | x| =10

=> |x|=15

=> x thuộc { 15 ; -15}

Vậy c thuộc { 15 ; -15}

a) \(\left|x+5\right|+3=7\)

\(\left|x+5\right|=7-3\)

\(\left|x+5\right|=4\)

TH1: x + 5 = 4

x = 4 - 5

x = -1

TH2: x + 5 = -4

x = -4 - 5

x = -9

Vậy x ∈ { -1; -9 }
