Ok theres the quick overview of what we did in class. Sorry if I missed some things, I got the main points down I think. Homework was
And today for homework.
(2x)(3x)
which means (2)(3)(x)(x)
(2)(3) =6
(x)(x) = x^2
So (2x)(3x)=
=6x^2
Then dividing.
6x/-3x = -2x
A) 4n+7+5n+6= 9n + 6
B) This could represent the difference between each squirrel.
C) (5n-1)-(4n+7) = 5n-1-4n-7
= n-8
* remember that when the negative is outside the brackets whatever inside is the negative*
Next Question #15 from the Chapter 5 practice test.
A) $100+5b b=bowling shoes
B) $20+4b b=pizza
C) 100 + 5b + 20 +4b = 120+9b
D) 120+9(9) =120 +81
= $201
~CHAPTER 7 ~
Multiplying and Dividing polynomials.
one thing to know about negative and positive numbers.
(-)(-)= +
(+)(+) = +
(-)(+) = -
(+)(-) = -
(-)/(-) = +
(-)/(+) = -
(+)/(+)= +
so (2x)(3x)= 6x(squared)
* reminder (-2x)(4x) the first set is on the side so -2x would be on the side, the second set is always on the top 4x would be on top*
Another example using algebra this time .

math links,
Foldable.
I just touched on a bit we did on class, sorry if i missed something, comment please.
The next scribe is Simran.
Third. Multiply.
Almost Done. C) First replace the Q's with -3.6
Second. First I thought that you subtract fractions, but then i remembered that we haven't learned how to subtract fractions THIS year yet.
So you divide the decimals. 4.5/ -3.6 - -3.6/4.5
Okay so there it is. Sorry for it being so long. Comment please.
Natural Numbers are first they are numbers that we use everyday like 1,2,3,4,5,6,7
Then it is Whole Numbers 0 and Natural numbers.
Then Itegers which are Whole Numbers and their opposites eg. -3,-2,-1,0,1,2,3
Then it Rational Numbers itegers that can be expressed as fractions.
After that Irrational numbers, numbers that can't be expressed as fractions. Eg PI.
Ok so, I hope i covered some major things.
So I hope that my post helped you understand 360. If I missed anything please comment.
