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 .

Good scribe shaaaany, haha. Nice pictures and good job explaining what we did in class.

Great scribe Shaneille! I like your pictures and examples. It was very colourful too and outstanding. You forgot to put the Challenges and the Signed test for HW but that's ok. Great job again!
