Question

Verify the following
18multiplied by (7+(-3)=(18 multiplied by 7)+(18 multiplied by(-3)

Answer 1

Answer:

Idk

Step-by-step explanation:

Answer 2

18*(7+(-3))=(18*7)+(18*(-3))

Since here a property is used that is distributive property that states that

lets take a,b,c are some constants then

According to distributive law

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

You can also solve LHS and RHS separately to get your answer.

LHS

18*(7+(-3))

=18*4

=72

RHS

(18*7)+(18*(-3))

=126+(-54)

=72

Hence LHS=RHS so it is proved
