- Redundant word: "school" (appears twice in the line)

- Redundant word: "are" (the correct phrase should be "They take off their coats...")
3. Line 3: "Some of the students go for to the laboratories and workshop where they learn in physics, chemistry, and art."
- Redundant word: "for" (the correct phrase should be "go to the laboratories...")
4. Line 4: "When a students is on duty, he comes to school very early."
- Redundant word: "a" (should be "When a student is on duty...")
5. Line 5: "He or she has to open all the window, water in the flower and clean the blackboard, so all everything is ready."

line 1: school (1)
line 2: are
line 3: their
line 4: for
line 5: in
line 6: students => student
line 7: very
line 8: in
line 9: all
line 10: to
Tổng số học sinh của lớp 4B và lớp 4C là 92-30=62(bạn)
Số học sinh lớp 4Blà (62+2):2=64:2=32(bạn)
Số học sinh lớp 4C là 32-2=30(bạn)
Qua B, kẻ Bm//a//b(tia Bm nằm giữa hai tia BA và BC)
Bm//Aa
=>\(\widehat{mBA}=\widehat{aAB}=40^0\)
Ta có: Bm//Cb
=>\(\widehat{mBC}=\widehat{bCB}=180^0-130^0=50^0\)
\(\widehat{ABC}=\widehat{mBA}+\widehat{mBC}=40^0+50^0=90^0\)
a. Dãy số a có quy luật tăng 3 đơn vị sau mỗi số hạng. Vì vậy, 3 số hạng tiếp theo sẽ là 24, 27, 30. b. Dãy số b có quy luật tăng 5 đơn vị sau mỗi số hạng. Vậy, 3 số hạng tiếp theo sẽ là 40, 45, 50. c. Tổng của 20 số hạng đầu tiên của dãy số a sẽ là 15 + 18 + 21 + ... + 66. Tương tự, tổng của 20 số hạng đầu tiên của dãy số b sẽ là 20 + 25 + 30 + ... + 95.
a. 20 số hạng có số khoảng cách là:
20 – 1 = 19 (khoảng cách)
Tổng khoảng cách là:
3 x 19 = 57
Số hạng thứ 20 của dãy là:
15 + 57 = 72
câu b làm tương tự nha bạn
Ta có: AB//DC
=>\(\widehat{A_1}=\widehat{D_4}\)(hai góc so le trong)
=>\(\widehat{D_4}=110^0\)
Ta có: \(\widehat{D_1}=\widehat{D_4}\)(hai góc đối đỉnh)
mà \(\widehat{D_4}=110^0\)
nên \(\widehat{D_1}=110^0\)
Ta có: AB//DC
=>\(\widehat{C_3}=\widehat{B_2}\)(hai góc so le trong)
=>\(\widehat{B_2}=135^0\)
Ta có: \(\widehat{B_1}+\widehat{B_2}=180^0\)(hai góc kề bù)
=>\(\widehat{B_1}=180^0-135^0=45^0\)
