Question

if a=-5,b=4cm and c=-2,verify that: (1) a+(b+c)=(a+b)+c and & a*(b+c)=a*b+a*c​

Answer 1

Answer:

1)-3 and 2) -10

Step-by-step explanation:

1)a+(b+c)=(a+b)+c

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

-5+2=-1-2

-3=-3

2)a*(b+c)=a*b+a*c

-5*(4-2)=-5*4+-5*-2

-5*2=-20+10

-10=-10

Answer 2

Answer:

a=-5,b=4,c=-2

Step-by-step explanation:

by putting the given value

1)-5+(4+(-2)=(-5+4)+(-2)

or,-5+(4-2)=(-5+4)-2

or,-3=-3
