Distribution, the AREA MODEL, and Combining Like Terms
fyi... if there are NO QUESTIONS posted to the blog, I will not be a happy camper if you need help with the homework on Tuesday!
the following passage is from "Turning to one another: simple conversations to restore hope to the future" by Margaret J. Wheatley
We can't be creative if we refuse to be confused. Change always starts with confusion; cherished interpretations must dissolve to make way for the new. Of course it's scary to give up what we know, but the abyss is where the newness lives. Great ideas and inventions miraculously appear in the space of not knowing. If we can move through the fear and enter the abyss, we are rewarded greatly. We rediscover we're creative.
Im ready Mr.Chamberlain!!!!!!!!!:I
ReplyDeleteOk so im confused on 1b. it says subtract but i forget whether you make the subtraction symbol a addition symbol or not. Can somone help?
ReplyDeleteThe problem in 1b is:
ReplyDelete-8(x-3)
If you like, you can CONVERT ANY subtraction statement into an addition statement by ADDING THE OPPOSITE. So, an equivalent expression would be:
-8[x+(-3)]
The -8 is distibuted to both TERMS, so that the expression can be expanded to:
-8(x) + (-8)(-3)
This expression simplifies to:
-8x + 24
which is now in SIMPLEST FORM!
PLEASE DO NOT WORRY IF SOME OF THE HOMEWORK CONFUSES YOU... WE WILL BE GOING OVER THE DISTRIBUTIVE PROPERTY IN DETAIL ON WEDNESDAY!
Mr. C.
Allow CONFUSION into your life...
