(x+4x+7x+....+25x)+(2+4+6+...+18)=324

117x  +   90 = 324

117x = 324- 90

117x=234

x=234/117

x=2

Đề 1 : Talk about your bestfriend

Hello everybody,my name is Vy.If you want me to tell you about one of my friends,I will think about my best friend firstly.

Her name is Duyen.If you ask : "How does she look ".I will answer : She is tall but slim,she has an oval face with straight nose,big eye, warm slime, and long black hair.I think a Vietnamese girl her is very beautiful.And what about her personality ? She is friendly,careful,kind,.....all good personality that one can have.Not only that, she is a very kind person. Always open your heart to everyone, share, encourage  when you are sad, encourage you to do something you want or even happier than you when you get good things.Duyen want to be a teacher, her mother so she studies very hard and always gets good marks but she never arrogant.Duyen is also a funny girl,she always makes me laugh so much when we meet each other.We always play,study and many many activities together.

Maybe later we will not learn or even meet again but I still want to keep the memories of this beautiful friendship in the heart, forever ...

Finally,I want to say to every body : "“Best friends are the people in your life that make you laugh louder, smile brighter and live better”

---------------------------------------------------------Let the sweet friendship refresh your soul----------------------------------------------------------------

Ta có: (1+x)*x:2=210

=> (1+x)*x=210x2

=> (1+x)*x=420

Vì 1+x và x là 2 số tự nhiên liên tiếp và 420=20*21

=> x=20

S=  (1-2) + (3-4) +... + (2001 - 2002) + 2003

S = -1 + (-1) +.... + (-1) + 2003

S = -1 x 1001 + 2003

S = -1001 + 2003 = 1002
