Bonjour,
C: 14(a+2)
D: a(7+12) = a* 19 = 19a
E: a( 7+2a)
F: 6( 3a+ 2)
G:4( 5a -1)
bonjour
A = 32 x 19 + 32 x 11
A = 32 ( 19 + 11 )
A = 32 * 30 = 960
B = 4 x a + 4 x 7
B = 4 ( a + 7 ) = 4 a + 28
C = 14 a + 28
C = 14 ( a + 2 )
D = 7 a + 12 a
D = a ( 7 + 12 ) = a x 19 = 19 a
E = 7 a + 2 a²
E = a ( 7 + 2 a )
F = 18 a + 12
F = 6 ( 3 a + 2 )
G = 20 a - 4
G = 4 ( 5 a - 1 )
