Write in simpliest form: -8(1.2c-3.3d)

OpenStudy (shane_b):

Do you know how to distribute the -8 to both terms?

OpenStudy (shane_b):

Here:\[(-8)(1.2c)+(-8)(-3.3d)\]Now just multiply that out...it's that easy :)

I got 9.6c-26.4d can someone tell me what I did wrong? because its wrong..

OpenStudy (shane_b):

You got both of your signs backwards. Do you know your sign rules?

OpenStudy (shane_b):

(-)(-)=+ (-)(+)=- (+)(+)=+

OpenStudy (anonymous):

I'm more confused..

OpenStudy (anonymous):

Translation of what Shane said: A negative times a negative = a positive A positive times a negative = a negative A positive times a positive = a positive

OpenStudy (anonymous):

-9.6c+26.4d?

OpenStudy (anonymous):

Yes
