Hello everyone
Im the scribe thing what ever you call it for today anyways in class today we didn't do a mental math i was so happy about that well what we did do was area how to find it in rectangle and others.
Well also we had to work on mutiplying polynomials it was easy i say, well here are some examples:
(3a)(2b)=6ab
(-2f)(-5f)=1oF2
(4e)(-3e)=-12e
stuff like that we had to do and more but here is what was on the other side of the page:
5(x+3) = 5x+5 . 3 = 5x+15
5(x-3) = 5x-5 . 3 = 5x-15
2(x+6) = 2x+12
Here was someother thing that we had to do
8+3(x+2)
8+3x+6
3x+14
that was a question on the other page that i had to do
I hope this scribe wasn't to weird well bye bye

aLisagood job stephanie. i see your actually keeping up ith the blog :) well i see few minor errors, not very noticeable (:
(-2f)(-5f)=1of²
this qestion you forgot to add in the exponent. so the answer is -12e²
(4e)(-3e)=-12e²
Another thing i should point out is, if you want to use a dot to show multiplying it'll be more understandable if the dot was in the center either than a period because people might think of it as a decimal.
5(x+3) = 5x+5 • 3 = 5x+15
5(x-3) = 5x-5 • 3 = 5x-15
2(x+6) = 2x+12

I got it now Steph! These are perfect examples to have included for our upcoming quiz tomorrow. I like how you showed the middle step for multiplying a monomial by a binomial. How do you think you could have used color or spacing to enhance your work?
Keep it up!
