Question

5 nhân x +3 nhân x=109

189:x-37:x=8

giúp mình nha

Answer 1

\(5\left(x+3\right).x=109\)

\(=>5x^2+15x=109\)

\(=>5x^2+15x-109=0\)

Answer 2

\(5.x+3.x=109\)

\(x.\left(5+3\right)=109\)

\(x.8=109\)

\(x=\frac{109}{8}\)

b) \(189:x-37:x=8\)

\(x:\left(189-37\right)=8\)

\(x:152=8\)

\(x=8.152\)

\(x=1216\)

Answer 3

\(5\left(x+3\right).x=109\)

\(=>5^2+15x=109\)

\(=>5^2+15x-109=0\)

     Đáp số : \(0\)

Answer 4

5 nhân x + 3 nhân x = 109

x nhân ( 5 + 3 ) = 109 x nhân 8 =109

x nhân 8 = 109

 x = 109 : 8

x =???

Answer 5

\(5\left(x+3\right).x=109\)

\(=>5x^2+15x=109\)

\(=>5x^{2^{ }}+15x-109\)

\(=>0\)
