Question

2) Verify distributive property of the following. -18{ 7+(-6)} = -18×7 + -18×(-6). ​

Answer 1

Step-by-step explanation:

To prove:

-18{ 7+(-6)} = -18×7 + -18×(-6)

Proof:

LHS = -18{ 7+(-6)}

= -18 { 1}

= -18

RHS = -18×7 + -18×(-6).

= -126 + 108

= -18

Since,

LHS = RHS

Therefore,

-18{ 7+(-6)} = -18×7 + -18×(-6) (Proved Distributive property)
