Summer vacations are the best time to relax and enjoy with family and friends, it’s the time I eagerly waited for every year. This year’s summer vacation is so special to me because it was the first time I’ve been on a trip with my colleagues. We had a wonderful time in Vung Tau – the city which has most beatiful beaches in Vietnam.

We stayed there for 2 days at a small but convenient hostel. First day, we got up early to see the sunrise on the beach. It’s the most gorgeous thing I’ve ever seen. Then we swam and lay down on the sand to enjoy beautiful sunlight and the clear blue sky. We also enjoyed delicious seafood and drank fresh coconuts.

The next day, it took us about 30 minutes to hike up the Small Mountain to visit the Lighthouse. But it was really worth the try! The lighthouse affords a panoramic magnificent view of the whole of Vung Tau and is a really interesting site. On top of Small Mountain, there is the enormous 28m figure of Jesus gazing across the East Sea. This is the largest sculpture in the Southern Vietnam. The two shoulders of the figure are balconies, each able to accommodate up to six people, which offer a splendid view of the surrounding landscape.

The weather during the time we stayed was really good and the local people were friendly. We took many photographs to save our memorable vacation and bought a lot of souvenirs, too. I just had so many good memories of that whole trip. Everything was great, but what made the trip even greater was the fact that I was able to bulid a stronger relationships with my colleagues.

x² = 400

x² =20²

=>x=20

Vậy x=20

K nha

Ta có : x² =400 

<=> \(\orbr{\begin{cases}x^2=20^2\\x^2=\left(-20\right)^2\end{cases}\Leftrightarrow\orbr{\begin{cases}x=20\\x=-20\end{cases}}}\)

Vậy x = { 20 ; -20}

Diện tích khu vườn hình chữ nhật là:

40 . 55 = 2200 (m²)

Vì bao quanh vườn là lối đi có chiều rộng 2m nên diện tích khu vườn và lối đi là:

(40 + 2 + 2)(55 + 2 + 2) = 2596 (m²)

Diện tích lối đi là :

2596 - 2200 = 396 (m²)

Số tiền để lát gạch lối đi là :

396 . 50000 = 19800000 (đ )

a)  biogas is dangerous

b) I love a person

c) I love road

d) my dog is expensive

e) my bell is  expensive

g) all of my kets are expensive

I biogas because its very delicious :))

a) -20 < x < 21

\(\Rightarrow x\in\left\{-19;-18;-17;...18;19;20\right\}\)

Tổng là : -19 + (-18) + (-17) + ... + 18 + 19 + 20 = 20

b) -18 < x < 17

\(\Rightarrow x\in\left\{-18;-17;-16;..15;16;17\right\}\)

Tổng là : -18 + (-17) + (-16) + ... + 15 + 16 + 17 = -18

c) -27 < x < 27

\(\Rightarrow x\in\left\{-26;-25;-24;..;25;26;27\right\}\) 

Tổng là : -26 + (-25) + (-24) + ... + 25 + 26 + 27 = 27

d) |x| < 3

\(\Rightarrow x\in\left\{1;-1;2;-2;3;-3\right\}\)

e) |-x| < 5

\(\Rightarrow x\in\left\{1;2;3;4\right\}\)

Hc tốt

Bài làm

a) Ta có: -20 < x < 21

=> x = { -19; -18; -17; -16; .... ; 17; 18;19;20 }

Lại có: -19 + ( -18 ) + ( -17 ) + ( -16 ) +...+ 16 + 17 + 18 + 19 + 20

= ( 19 - 19 ) + ( 18 - 18 ) + ( 16 - 16 ) + ( 15 - 15 ) + ... + ( 3 - 3 ) + ( 2 - 2 ) + ( 1 - 1 ) + 0 + 20

= 20

Vậy tổng x = 20

b) -18 < x < 17

=> x = { -18; -17; -16; -15; ... ; 15; 16; 17 }

Ta có: -18 - 17 - 16 - 15 - .... + 15 + 16 + 17

= ( 17 - 17 ) + ( 16 - 16 ) + .... + ( 2 - 2 ) + ( 1 - 1 ) + 0 - 18

= -18

Vậy tổng x = -18

c) Vì -27 < x < 27

=> x = { -26; -25; ... ; 25; 26; 27 }

Ta có: -26 - 25 - 24 - ... + 25 + 26 + 27

= ( 26 - 26 ) + ( 25 - 25 ) + .... ( 2 - 2 ) + ( 1 - 1 ) + 0 + 27

= 27

Vậy tổng x = 27

d) Vì | x | < 3

=> x < | 3 |

=> x < -3 và 3

Nên -3 < x < 3

=> x = { -3; 3; -2; 2; -1; 1; 0 }

Ta có: -3 + 3 - 2 + 2 - 1 + 1 + 0

= 0

Vậy tổng x = 0

e) Vì | -x | < 5

<=> x < 5

Nên x là số nguyên dương.

=> x = { 0; 1; 2; 3 ; 4 ; 5 }

Ta có: 0 + 1 + 2 + 3 + 4 + 5

= ( 2 + 3 + 5 ) + ( 1 + 4 ) + 0

= 10 + 5

= 15

Vậy tổng x = 15.
