bonjour

[tex]4 n + ( 3 n + 1 ) = 4 n + 3 n +1 = 7 n + 1 \\\\13 k - ( 2 k + 4 ) * 10 = 13 k - 20 k - 40 = - 7 k - 40\\\\( - 2 + t ) - t = - 2 t - t^{2} \\\\17 - 2 x ( - 5 - x ) = 17 + 10 x - 2 x^{2} \\\\8 m + 4 + ( - 2 m - 5 ) = 8 m + 4 - 2 m - 5 = 6 m - 1 \\\\8 ( 5 x + 2 ) + 3 = 40 x + 16 + 3 = 40 x + 19 \\\\[/tex]

Réponse : 4 n + ( 3 n + 1 ) = 4 n  + 3 n +1  =  7 n + 1 \\\\13 k - ( 2 k + 4 ) * 10  = 13 k  - 20 k - 40 =  - 7 k - 40\\\\( - 2 + t ) - t =  - 2 t - t^{2} \\\\17 - 2 x ( - 5 - x ) =  17 + 10 x - 2 x^{2} \\\\8 m + 4 + ( - 2 m - 5 ) =  8 m + 4 - 2 m - 5  = 6 m - 1 \\\\8 ( 5 x + 2 ) + 3 =  40 x + 16 + 3 = 40 x + 19 \\\\

j'espere que sa vas t'aider
