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!
