Nằm cạnh bên trường Tiểu học là trường trung học cơ sở.Từ xa nhìn lại, ngôi trường như một bức tranh phong cảnh tuyệt vời với những màu sắc tươi sáng: màu ngói đỏ, màu tường vàng nổi bật giữa nền xanh cây lá. Qua chiếc cổng sắt lớn là vào đến sân trường tráng xi măng phẳng phiu. Trước cửa phòng Ban Giám Hiệu, chiếc cột cờ bằng thép vươn cao. Trên đỉnh cột, lá cờ đỏ phấp phới bay. Mỗi gốc bàng, gốc phượng đều được xây bồn gạch hình tròn xung quanh cao khoảng gang tay, quét vôi trắng xóa. (Sân trường là nơi học sinh toàn trường tập trung chào cờ vào tiết thứ nhất của ngáy thứ hai hằng tuần, cũng là nơi học sinh tập thể dục giữa giờ theo nhịp trống và nô đùa thoải mái dưới bóng cây râm mát.)- câu tồn tại-

Giả sử không cs a điểm nào thẳng hàng thì ta vẽ được:
\(\dfrac{15.\left(15-1\right)}{2}\)=105 ( đường thẳng)
Số đ/t dôi ra là:
105-96=9( đường thẳng)
Ta có:
\(\dfrac{a.\left(a-1\right)}{2}-1=9\)
\(\dfrac{a.\left(a-1\right)}{2}=9+1\)
\(\dfrac{a.\left(a-1\right)}{2}=10\)
=> a.(a-1)=10.2=20=5.4
=> a= 5
Vậy a=5

72 –3.|x + 1| = 9
3.|x+1|=72-9
3.|x+1|=63
|x+1|=63:3
|x+1|=21
=> x+1= 21 hoặc x+1= -21
=>x = 21-1 hoặc x= -21-1
=>x =20 hoặc x=-22
Vậy x= 20 hoặc x= -22
