mình làm cách cấp 1 nhé
(x+1)+(x+2)+(x+3)+........+(x+100)=5750
=> (x+x+...+x)+(1+2+3+...+100)=5750
=> (x.100)+(1+100).100:2=5750
=> (x.100)+5050=5750
=>x.100=5750-5050
=>x.100=700
=>x =700:100
x = 7
Tim x biet (x+1)+(x+2)+(x+3)........+(x+100)=5750
tim x biet (x+1)+(x+2)+(x+3)+⋯+(x+100)=5750
cau1tinh
a) A=4+ 2 mu 2 + 2 mu 3 +... +2 mu 20
b) tim x biet
(x+1) + (x+2) +...+(x+100)=5750
tim x biet : (x+1)+(x+2)+.....+(x+100)=5750
tim x biet N thuoc

giup mk nha cac ban , mk dang can gap lam
Tim x,biet :a)(x+5)(x-2)<0
b)(x+1)+(x+2)+(x+3)+............+(x+100)=5750
Bai 1: Tim so tu nhien x, biet
(x+1)+(x+2)+(x+3)+....+(x+100)=5750
Bai 2; Tinh nhanh

Cac ban tra loi nhanh ho minh nha minh tick cho
tim y , x biet
( x - 1) ( 2y + 3 ) = 24
( x- 5 ) ( x + y ) = 12
( x + 1 ) ( x + 2 ) + ... + ( x +100 ) = 5750
Tim so nguyen to p de : p + 1, p + 2, p + 3 , p + 5 cung la so nguyen to
Cac ban giup minh nhe ! Hom nay minh phai di hoc roi
tim so tu nhien x,biet
a, 2x+3x=1505
