==  Posting  :  I think the word sole does not belong in the group of words. I think that that word sole does not belong there because of the clue, German folk tale enchantment is when objects are given human like characteristics and traits. Therefore, sole has nothing to do with this. Sole is the bottom surface of one's foot. It is not an object. ==

 Name: Jeff Schecter  Date: 3/11/10  Type of posting: 1  Posting: I think that the word sole doesn't belong in the group of words. Sole is an item. Sole is the bottom of a shoe. This doesn't belong because it isn't an actual object that is itself. There also hasn't been German folk tales about human soles. I think pink doesn't fit also. Pink is color and part of a description. Pink is not an object.

The rest of the words can fit into the categories, attempting to be educational, and by no means is pink educational. Also, no German folklore include the color pink, at least the ones I am aware of. <span style="color: #ff007c; font-family: 'Comic Sans MS',cursive; font-size: 17px;"> Name: Max Mongiello <span style="color: #ff007c; font-family: 'Comic Sans MS',cursive; font-size: 17px;"> Date: 3/10/10 <span style="color: #ff007c; font-family: 'Comic Sans MS',cursive; font-size: 17px;"> Type Of Posting: 1 <span style="color: #ff007c; font-family: 'Comic Sans MS',cursive; font-size: 17px;"> Posting: Hello everyone, How are you doing today? I think the word that does not belong is "pink". This is because it is a adjective and all of the other words are nouns. Also "pink" has nothing to do with German folk tales so it does not fit the description of the clues.

The equation was -c(11c+4). My answer was -11c+-4c. I don't think it was right. So my question is would the exponent be negative?

There is just one more monomial. The problem you are talking about is (k + 4) (k^2 + 3k - 6). You multiply k and k^2 so you will get k^3. Then you do the same thing for k and 3k. It equals 3k^2. You are not done yet. You have to multiply -6 and k so it is -6k. So far you have k^3 + 3k^2 -6k as your answer. Don't forget about the 4 in the first parenthesis. When you complete this, your final answer will be k^3 + 7k^2 - 18k - 24. Hope this helped.

= <span style="color: #ff6300; font-family: 'Comic Sans MS',cursive; font-size: 17px;"> For tonight's homework, I was confused about combining like terms. When you have two alike terms with an exponent (i.e. t^2 and 2t^2) does the exponent remain the same or would that be 3t^4? Please let me know. Thanks :) =

Name: Hailey Personette =] Date: 3/10/10 Type of Posting: 3? Hey Paige! It depends if you are adding, subtracting, multiplying or dividing. If you are adding, exponents remain the same. But if you are multiplying, the exponents get multiplied too. So ex: t^2 X t^2 = t^4. Hope i've helped !

**Name:** Jon Libock **Date:** 3/10/10 **Type of posting:** 3 **Posting: Well Paige it depends, when combining are you multiplying of adding because if your multiplying it would be 2T^4 and it your adding it would be 3T^2. If can notice if your multiplying you add the exponent and multiply the number, and if your adding you would add the number and keep the exponent the same, but you only combine terms with like exponents**

For number 20, I used foil and got my second line. I got t3 + 2t2 + 4t + t2 + 2t + 4. My answer that i got was t3 + 3t2 + 6 + 4. I am not sure if that is right or not, but that is what i got. What did anyone else get? Thanks for your time guys. Have a great evening :)

**Name: Kennedy Clifford** **Date: 3/11/10** **Type of posting: 3** **Hey Nick. Sorry for the late response. For number 20 on the evens of last night’s homework, I have the same second line as you ( t3 +2t2 + 4t + t2 +2t +4 ), and I did get the same answer as you ( t3 + 3t2+ 6t + 4 ). In your answer you forgot to put the (t) after your 6, and you did not put it in standard form ! When this problem is in standard form it should be 3t2 + t2 +6 +4. Just remember to put the answers into standard form .**

Posting: Hey everyone, how is it going, when I was doing my homework last night on page 462 I was trying to use the shortcut on number 19. The question is (2g+5)^2. I was thinking if I should distribute the power of 2 to each number, but I was not sure, please help, thanks.

<span style="color: #0036ff; font-family: 'Comic Sans MS',cursive;"> **Hey Corey, you have to do: (2g + 5) (2g + 5). Your answer to this would then be 4g^2 + 10g + 10g +25 but you can simplify. Your final answer would then be** **__4g^2 + 20g + 25__** **__.__ Also, you cannot do the short cut when it is like terms only when it is one subtraction and one addition. I hope this helped!!!**

Name: Marissa Moschella Date: 3/11/10 Type of Posting: 1 Good evening Corey! Don't worry; the problem you are having is a common misconception. I believe the shortest method is for you to square the 2g and the 5, then multiply the two numbers inside of the parenthesis together twice ( 2g x 5 + 2g x 5 ) making your answer 4g^2 + 10g + 10g + 25 which simplifies to 4g^2 + 20g + 25. I hope I was able to help, have a great night!

Name: Remzi Tonuzi Date: 3/12/10 Type of Posting: 3 Hi Mara. For the pie problem, it would be squared, so (2x+4)^2 so it would be (2x+4)(2x+4) and you would use Foil. So it would be A=(pie) 4x^2+16x+16. Hope that helped.
