Question

aidez moi svp

B = ( 8 - 10 ) * (-3) + 3

C = [(-4)*(-2-1)+(-8) diviser (-4)]*(-2)+2

Answer 1

Bonjour,

[(-4)*(-2-1)+(-8)/ (-4)]*(-2)+2

= [ (-4 * -3) +2 ] ( -4)

= (12+2) * -4

= 14 * -4

= -56

B = ( 8 - 10 ) * (-3) + 3

= -2* -3 +3

= 6+3

=9

Answer 2

B = -2 * (-3) + 3
B= 6 + 3
B = 9

C= [(-4)*(-3)+(-8)/(-4)]*(-2)+2
C= [12+(-8)/(-4)]*(-2)+2
C= [12+2]*(-2)+2
C= 14*(-2)+2
C=-28+2
C= -26
