Answer:
Verified
Step-by-step explanation:
1. a =-10 ,. b= 7 ,, c= -3
LHS: a+ (b+c) = -10 + (7-3) = -10 + 4 = -6
RHS: (a+b) + c = ( -10 + 7) + (-3) = -3 -3 = -6
hence as LHS =RHS ,
HENCE PROVED .
2. LHS: a× (b+c) = -10 × (7-3) = -10 × 4 = -40
RHS: (a×b) + (a×c) = (-10×7 ) + ( -10×-3) = -70 + 30
= -40
Hence as LHS = RHS
HENCE PROVED
PS. This is also called Distributive property .

Answer:
Step-by-step explanation:
a+(b+c) =(a+b) +c
LHS: a+(b+c)=-10 +(7+(-3))=(-10)+4=-6
RHS: (a+b) +c=(-10+7) +(-3) = -6
hence verified
b) a x (b + c) = (a x b) + (a x c)
LHS: a x (b + c) = -10 * (7-3)=-10* 4=-40
RHS: (a x b) + (a x c)= (-10*7)+(-10*-3)=-70+30=-40
hence verified
