    I can't figure out where the error was on question 25, page 117. I have a suspicion that it has to do with the distribution, but I can't figure out how.

    You're right, Paul the problem is in the distribution step... go back and look at the GIVEN information... a=b, right?

    What would P/GEMDAS do with the distribution step, based on the fact that a and b are equivalent.

    lmk is this helps

    For p 117 #13 proof step 2 seems to be the Same as step three, is it?

    Would #1 on pg 116 follow the Transitive Property of Equality or the Transitive Property of Congruence?

    I'm not sure what reason to put for #5 Reason a. on page 117! Would it be Distributive Property?

    GREAT QUESTION For #13, step 2... YOU WILL GET THIS WRONG ON THE TEST... look for a postulate or definition (based on the GIVEN) that is the REASON for step 2 (it is NOT the same as step 3)

    ANOTHER GREAT QUESTION on pg 116#1...

    MEASURES (like degrees, inches, feet, cm) speak to equivalence...

    GENERAL SHAPE AND SIZE speak to congruence...

    remember your blog etiquette... and lmk if this helped...

    117#5, is actually referring to HOW the current statement was made flowing from the previous statement... what was done?? 10 was added to both sides, yes? ADD POE, yes?

    For pg 117 #5, I meant for Step 2. What would the property be when you multiply two sides by 2? Would it be multiplication POE?

  10. Mr. ChamberlainOctober 9, 2011 at 7:14 PM

    Yup, MULT POE FOR 117#5 step 2

    I really can't find anything wrong with #25.. They did everything correctly, but it doesn't seem true that a=2a...

    I'm not sure if this is right, but it never showed anywhere that a=1 or b=1 for #25? Could that be the error?

  13. Mr. ChamberlainOctober 9, 2011 at 7:25 PM

    To get from line4 to line5 in #25, she divided by (a-b)... given that the GIVEN in line 1 is true, what is (a-b) always equal to? Can you divide by that number... EVER???

    Sorry! I just read your explanation to Paul. I see the problem in the Distribution step.. Is it that b^2-a^2 was "undistributed" incorrectly? Because then if you distributed what they gave you it would give you (ab^2-ba^2)?

    Could you go over #38 on the Chapter Review pg 132 in class tomorrow? I'm still kind of struggling on how to MAKE a Statement/Reason chart without any aid.. Thanks!
