Factoring Book

Today, you were assigned a small project on factoring.  You goal is to create a book that describes the different strategies of factoring a trinomial. You will explain each strategy, give two worked out examples, and 3 problems for each strategy and include a complete answer key to the problems in the back of the book.

•          GCF
•          “Diamond Problem” or the equivalent
•          Difference of Two Squares
•          Perfect Square Trinomial
•          When the x² coefficient is greater than 1

The project is due in one week, Thursday, May 5th.  

Chapter 1-12 Review

Please remember that we have the first portion of our test tomorrow, short response.  This is a cumulative test, so please review EVERYTHING!  =)

Here are the answers to your worksheet that you got yesterday in class:
1) x = 12; y = 33
2) x = 25; y = 58
3) many acceptable answers...
4) x = 27.6
5) x = 47.0
6) x = 5.3
7) 1980 degrees
8) 1080 degrees
9) 3600 degrees
10) 540 degrees
11) Kite; segement PQ is congruent to segment PS; segment QR is congruent to segment SR and they are pairs of congruent sides
12) Trapezoid; segment PQ is parallel to segment SR and segment PS is not parallel to segment QR
13) Parallelogram; segment QR is parallel to segment to PS and segment RS is parallel to segment QP
14) Rhombus; segment PW is parallel to segment RS, segment PS is parallel to segment QR and segment QS is perpendicular to segment PR
15) Translate down 5 and left 2, then reflect over the y-axis
16) Rotate 90 degrees counterclockwise about the origin, then translate down 6 units.
17) 2
18) 1
19) 8
20) (x + 3)^2 + (y - 2)^2 = 64
21) (x - 6)^2 + (y +1)^2 = 98
22) 5:3
23) 13:15
24) radical 3: 2
25) 120.6 square ft; 683.6 square feet
26) 236.0 square cm; 295.0 square cm
27) S = 226.73 square cm; V = 209.44 cubic cm
28) S = 142 square ft; V = 105 cubic ft
29) S = 389.56 square m; V = 458.90 cubic m
30) S = 345.70 square in; V = 378 cubic in
31) S = 78.54 square ft; V = 65.45 cubic ft
32) S = 251.14 square in; V = 290.98 cubic in

Chapter 1-12 Review

For review, please complete P. 866 #1-18 ALL.
Finish your Chapter 12 Study Project (see post below for terms)
Study for our Cumulative Test on Ch. 1-12 on Thursday (Short Response) and next Thursday (Multiple Choice)!!

12.7- Similar Solids

Today we did an investigation on Similar Solids, and discovered the relationships of the surface areas and volumes of similar solids.  If you were absent, please do the investigation from your textbook on Page 846.

Tonight's homework  is P. 850-851 #3,7,9,16,17, and 21.
