Today we didn't really do a lot, we finished our homework and go0t started on our new homework which was:
-Read page 254 to 259
-7.1 check you're understanding number 2
-Practice number 3,5,7,9,10,12,15 and 16
-Apply number 17 to 23
-Extend one of 24 to 27
We also have to turn in our stash-its with:
-Chapter 5 Self Evaluation
-Similarity Test Signed
-Chapter 5 Test Signed
-One Of The Two Chapter 5 Challenges
And that's all we did in class so get ready for the dance!

Math class today was pretty simple. We just went over our test, got homework and went over some definition words for Chapter 7.

These are Today's notes:(with pictures)

Monomial ----> give three examples using variables for at least two.
3x, -4t, 7s,

Binomial ----> give three examples with a constant.
4x+19, 4x + 13x2, 3x - 2y

Polynomial ----> an algebraic expression with four or more terms.
Ex: -4x2 + 4x + 3y + 4

Distributive property:
a (x+y) = ax + ay
a (x-y) = ax - ay
-a (x+y) = -ax - ay
-a (x-y) = -ax - ay

(Sorry the picture button doesn't work i'll edit when it works)

The next scribe is Jonathan.

Hey guys, so today in math we had a test review so in this scribe im going to talk about what will be on the test.

First off lets name the parts in this number.

So 7 is the Numerical Co-Efficient
The X is the Varible
The 2 is the exponent
and the constant is -9, when your talking about constants you have to put the whole thing.

Alright now its time to learn aboot LIKE TERMS!!

Like terms are 2 or more numbers that go together. The reason they go together is because they have the same variable and the same degree. Lets try an example shall we?

Which Numbers are Like Terms?

7x + 5y + 9xy + 4y

The like terms are 5y and 4y because they have the same variable which is "Y" and the same degree which is 1.

Now lets do a question like one we'll probably get on the test.

(7x + 4y + 8) - (3 + 6x -8y)

The first step we have to do is remove the brackets, now you think it would be

7x + 4y +8 -3 +6x -8y but you would be wrong if you thought that the correct answer is:

7x + 4y + 8 -3 -6x +8y. That is the correct way to write it, the reason you write it like that is because the symbol seperating the brackets is a "-" symbol so you have to change each number to its Additive Inverse.

An additive inverse is the opposite of a number. For example the additive inverse of
-1 would be 1 heres some more examples:
-6xy +6xy
-9y + 9y

Those are all additive inverses

Thats really all I can do for a scribe right now because the "import picture button" decided to stop working so I'll update this scribe once the "import picture button" decides to work. Sorry for the inconvienence.

Hewoo people of earth today I'm going to talk about what we did in math today.

Well the student teacher person went over LIKE TERMS. So these are some information on like terms.
  • They must have the same VARIABLE and DEGREE.
  • They can be grouped.
  • They can be +,-,x,÷


We also used algebra tiles to figure some of these questions out.


For this question we would have to find all the like terms. In other words put all the "ANIMALS" together.

Next Step:

This is when all of the " ANIMALS " .

Next Step:

For this step we had to put the animals together again and rearrange it. We have to use like terms to rearrange. ( look for the variables and the one that has the greatest degree).
and i think that was it for that math class. Sorry if i missed anything. Please tell me if i did.
Read 5.3
Check your Understanding # 1,3
Practice # 5,8,10-17,19,20,22,27,29

Hey guys, reNz P. here! bringing you , the things that we did today in math class.
(: Guess what? We just started a new unit. and its UNIT 5.

and it is all about:

So guys, now lets try to ANSWER this. 

25n = _____
495x + 18d + 16o = ________
6e+w+21 = ________
rp+is+cu+73 = _______
906 + s + d + b + 3st = _______


(: that's it for today guys, hoping that the next scribe will be way more better than this.

I am SO SO SORRY for all the MISTAKES ):.


It's the chapter 5 in our workbook. (:

hehehe *peace*

byee guys. Don't forget to comment.

Hey guys what we did is we answered numbers 11, 14 and 15 on our Textbook chapter 4.4. If you don't have your Textbook, click HERE(
Username is spmathgr9+(your textbook number) I'm sure you know the password.

Here are the answers:
11. Each side is 12cm long.
14. The scale factor is 7.5
15. The new tank will hold 770 liters of water.

Our assignment is to answer Chapter 4 review and study for our test.
I will give you the answers for #1 to #4 in chapter review.

1. A POLYGON is a closed figure with sides that are line segments.
2. SIMILAR figures have equal corresponding angles and proportional corresponding side lengths.
3. The SCALE FACTOR is the constant amount my which any dimension of a shape is enlarged or reduced.
4. A PROPORTION is a statement that says two ratios are equal.

Hello 9-06 today in math class we did 4.4 practice
#3 to 15 that's do tomorrow.
If you don't have Textbook you can go to website there you can do your Homework.

Sorry my Scribe is short because we didn't do much this

Math Test on Wendesday.
L.A or Social Studies tomorrow.

Next scribe is Jericho Toledo.
