what an expression equivalent -3(x-4)

Question

i have to find an expression equivalent to -3(x-4) and i think i have to use the destributive property

Answer 1

The distributive law is:

 

a·(b+c) = a·b + a·c

 

In your case, we have:

 

-3(x-4) = -3(x +(-4)) so a = -3, b=x, c = (-4)

-3(x-4)= (-3)x + (-3)(-4) = _____?
