Hlo army.. ​

Answer 1

Answer:

a) 18×(7-3) = (18×7)+(18×(-3))

18×4 = 126-54

72=72

b) -21×(-4-6)= (-21×-4)+(-21×+6)

-21× -10 = 84+126

210=210

Answer 2

Answer:

a) 18 × [7-4]=136+(-54)

18× 3= 136-54

54= 82

it is not equal

b) -21×[-4-6]= [(-84)+(-126)]

-21× (-10)=[-84-126]

-210= -210

it is equal

hope it helps you
