(-3+w+2v)(-6) get rid of parentheseis

OpenStudy (oaktree):

Same drill as last time. Multiply every term in the first parentheses by -6.

OpenStudy (anonymous):

how bout the w

OpenStudy (oaktree):

What's w*-6?

OpenStudy (oaktree):

Any variable times a constant (-6 is a constant because it will always be -6) is just the constant in front of the variable, right?

OpenStudy (oaktree):

So...what is w times -6?

OpenStudy (anonymous):

is it 18+-6w+-12

OpenStudy (oaktree):

Oh, my. What is +-? There is no such thing, right?

OpenStudy (oaktree):

And don't forget your v on the 12!

OpenStudy (anonymous):

7+-2 is the same as 7-2.

OpenStudy (anonymous):
