bonjour jai vraiment besoint daide merci davance <3


a=3 b= -4, c= -5 d= 7




H = a - b + c


I= 2a - 3b K= -5ac + bd

L = 2 (a-b) +d J= ac - bd

M = 5 (b - a) + d​

Sagot :

Réponse:

H = 3 - ( -4) + (-5) = 2

I = 6 - ( -12) = 18

K = 75 -28 = 47

L = 2. 7 + 7 = 21

J = -15 - (-28) = 13

M = 5.(-7) + 7 = -28

voilà ;)
