Question

Daca a xb = 42,iar c x a =24 ,calculeaza a x ( b - c ) : 2=

Answer 1

a ×b = 42
c × a =24
(a ×b) - (c × a) = 42-24
a× (b-c)=18
a × ( b - c ) : 2=18:2=9

Answer 2

a x b - a x c=a x (b-c) ,atunci inlocuim : 42-24=18 si 18:2=9 , deci a x (b-c) :2=9 . sper ca te-am ajutat! :) coronita? :) :)
