Answer 1

Answer:

hi bro /sis

Step-by-step explanation:

(a) LHS =18×[7+(−3)]=18×4=72

RHS =[18×7]+[18×(−3)] =126+(−54)=72 (verified)

(b) LHS =(−21)×[(−4)+(−6)]=(−21)×(−10)=210

RHS =[(−21)×(−4)]+[(−21)×(−6)]=84+126=210 (verified)

Answer 2

Step-by-step explanation:

LHS=7+(-3+2)

=7+(-1) =7-1 =6

RHS= [7+(-3)]+2

= [7-3]+2 = 4+2 = 6

LHS=RHS
