How do you simplify #-4( v - w ) + 2( - 2w - 6v )#?

Answer 1

Kennedy Adams

The answer is #-16v#.

#−4(v−w)+2(−2w−6v)#

First, distribute:

#-4v+4w-4w-12v#

Now combine like terms; sometimes it is helpful to put all sets of like terms together first:

#4w-4w-4v-12v#

#0w-16v#

#-16v#

#-4(v-w)+2(-2w-6v)# is equal to #-16v#

#-4(v-w)+2(-2w-6v)#

Multiply out the brackets.

#=-4v+4w-4w-12v#

Combine like terms(Like terms are the ones that have the same variable)

#=-16v#

You managed to simplify the expression.

Answer 3

Eva Abramson

To simplify -4( v - w ) + 2( - 2w - 6v ), first distribute the constants:

-4 * v = -4v -4 * (-w) = 4w 2 * (-2w) = -4w 2 * (-6v) = -12v

Then, combine like terms:

-4v + 4w - 4w - 12v

Combine the like terms:

-4v - 12v + 4w - 4w

-16v

So, the simplified expression is -16v.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
