trả lời câu hỏi bên dưới

Every day I return to my home after school. My house is located in the center of Hanoi city. The white house has 5 floors so I can see it from afar. My house does not have a yard or garden like the houses in the countryside.Step inside, first will be the living room. Here we have a television to watch movies together every day. I like it very much. The second floor is my parents bedroom. It is very neat. My room is on the third floor. I usually set up a lot of things here so it looks a bit cramped. But no problem, I still love it. The 4th floor is my father’s office. Every day he sat for a long time in it. On the top floor is the terrace. There is a lot of wind here.I liked the winds so I asked permission to bring my bed up here but my dad refused. Although climbing the stairs sometimes makes me tired, I still love my house very much

My hobby is playing games

rõ câu hỏi hơn đi bạn?

Mua 8kg gạo tẻ hết số tiền là: 22000 x 8 = 176000 (đồng)

Mua 6kg gạo nếp hết số tiền là: 30000 x 6 = 180000 (đồng)

Mua hết tất cả số tiền là: 176000 + 180000 = 356000 (đồng)

Cách 1: 

Ta có góc M1 và góc M2 là 2 góc kề bù

=> M1 + M2 = 180^o =>M2 + 120^o = 180^o => M2 = 60^o = N1

Mà M2 và N1 ở vị trí so le trong nên m//n

Cách 2:

Ta có N1 và N2 là 2 góc kề bù => N1 + N2 = 180^o

=> N2 + 60^o= 180^o => N2 = 120^o= M1

Mà N2 và M1 ở vị trí đồng vị nên m//n

7^{x +} 135 : 45 = 52

7^{x + 3 = 52}

7^x = 52 - 3

7^x = 49

7^x = 7²

Vậy x = 2
