Answer: Option 'B' is correct.
Step-by-step explanation:
Since we have given that
-4(x+3)= -4x - 12
It shows the property of "Distributive law".
As we know that
Distributive property states that
a × (b + c ) = a × b + a × c
where, a, b, c ∈ R
And we have dine the same thing with the given expression.
Hence, option 'B' is correct.
