a = 2(x+8) = 2x + 8x = 10x
b = 3(x-2) = 3x - 2x = x
c = 4(8+2) = 4*8 + 4*2 = 32 + 8 = 40
d = -3(x-7) = -3x + 21
e = -4(3-2) = -4*3 + -4*(-2) = -12 + 8 = -6
f = (5 - 1) x = 5x - x = 4x
Voilà je crois que c'est bon ce coup ci
Bonjour,
a=2(+8)
a=2X8
a=16
b=3(-2)
b=3X(-2)
b=-6
c=4(8+2)
c=(4X8)+(4X2)
c=32+8
c=40
d=-3(-7)
d=-3X(-7)
d=21
e=-4(3-2)
e=(-4X4)-(-4X2)
e=-16-(-8)
e=-16+8
e=-8
f=(5-1)x
f=(xX5)-(xX1)
f=5x-x
