I cannot find this answer anywhere on the internet I need it really badly! Also, if you can, tell me this word problem: The length of a rectangle is 5 times the width. The area is 125 square centimeters. What is the length?

Hi, Ariejas!

Are you being instructed in a class how to figure out what the correct answers are yourself, please?

Thanks!

Grrr... I have to do this for a review smart one... I need it, If you don't have an answer that I can use, then don't answer the question at all...

If you don't know how to answer the questions, then how will you be able to honestly say that you did well knowing how to do what you're supposed to know how to do?

This isn't the kind of site where people just plug in their questions and expect the answers to be spoon fed to them. If you want help in learning, that you will find here. But, you'll need to show some effort on your part first.

And, my post above, is indeed an answer that you can use!

Thanks!

Product means multiply
Consecutive even integers; Let one be x and the other x+2

thus: X(X+2) = 224
There are two solutions to this problem.

This one is WAY TOO EASY: The length of a rectangle is 5 times the width. The area is 125 square centimeters.

Area = L *W

You know Area and you W in terms of L; i.e. W=5L
Your turn.

A suggestion I always make on stuff with shapes is to draw a picture of it. Most people try to do math as a bunch of abstract numbers floating in the air with no meaning. If you draw it, you get a visual and see the relationships.

So draw the rectangle. The number you're solving for is the x. Look at the relationship between that and the length. The length is five times the width, so what expression can you make for the length in relationship to the width? Then plug that into your area formula, which you already have the answer to. Then solve for the x.

You can even sort of draw a picture about the two consecutive numbers if you make a number line and try to picture the relationship of the two numbers.

As a side note, our guidelines here are for you to make an attempt at your problem yourself first. Even if you can't solve it all the way, showing your attempts shows us that you've made some kind of attempt and are not just looking for someone to give you the answer, plus it allows people to see where you are going wrong. So don't dump on someone who is just following our homework guidelines.

Bet you don't prime factor license plate numbers on a trip for fun? I know someone who does. Rubik's cube was cake for him too.

This guy has another quirky trait. He'll play chess with someone while washing dishes without even seeing the board.

I played chess when I was a kid with someone over the phone.

KISS, quick question about post #5. You said two consecutive numbers would be X+ (X+2), shouldn't that be X+(X+1)?

Unknown008
May 27, 2010, 09:13 AM
Wow, I do play chess and solve Rubik's Cube in some five minutes... but from there to play over the phone or without looking at the board?

Prime factor license plate numbers? No, I need try to recall my lessons... I forget them so easily :(

Note post says consecutive even integers, hence +2

When a kid, you had lots of time and no money and NO COMPUTERS and no transportation unless it was a bicycle. Remember, a long time ago for me. Hence, playing chess over the telephone was something to do. We had our own board. I could not keep track of a chess board in my head. I can barely memorize anything.

Oh, that's better! :p

I know that one of the greatest chess player could play against a dozen players without looking at the boards... well, if that is true. Anyway, it's been quite some time since I didn't play a good chess match... and the exams are coming closer each day...

Oops, getting off-topic... :o

Ahh, poster has a very different title for his post than the actual problem he kisted. I was working on his rectangle problem

You have to remember to look at the title too. At least the way I learned to write is you restate the problem in the paragraph.

So, who's "up" for a game of chess on this site? :D

Unknown008
May 28, 2010, 08:31 AM
Actually I was thinking about it some time ago when I was dining... what about a chess game over the internet? :D

Like someone could start a thread, and play the moves one after the other. The only problem I see is one may not be sometimes able to play immediately... and trolls :eek:

Jeez, I haven't played chess for years. I remember the rules, but not how to actually play. OK, I'll move that pawn... now I'm stuck. LOL.

I think that it would be worth a try on a thread on this site!

If I can write sheet music, post it and have a way for people to be able to listen to it and/or print it out and play it, and you math people can post your fancy mathematical diagrams, explaining your brilliant answers, I'm sure that we can find a way to be able to have one or more games of chess on this site!

Trolls? We'll, the threads could be pre-arranged games with someone so that the threads wouldn't appear to be questions. Someone not knowleadgeable enough about the game of chess would also probably not be that likely to post on the threads.

Someone making intelligent comments on them, I think, might be beneficial to one or the other player, or perhaps both, though.

Thanks!

What about the 'Lounge'?

Clough
May 29, 2010, 12:02 AM
Why not in the Games forum topic area?

I was going to try to post an example of a game here where everything could be seen in an image. But, for the particular site that I had in mind to use, I lack the proper plugin!

Unknown008
May 29, 2010, 12:26 AM
Yes, maybe the Games section would be better...

I was thinking that since KISS could play over the phone, it'll be quite easy to play over the net.

You can say for example: Pawn d5 to move a pawn to the tile d5

Clough
May 29, 2010, 12:32 AM
Yes, describing the moves would work!

I'm trying to find an example game set-up for a visual. But, that's probably not going to be happening just yet...

So where do we go for that sheet music you were discussing? The Lounge? (I'm SO much better at sheet music than chess.)

Unknown008
May 29, 2010, 12:35 AM
Yes, I know what you are thinking about... If I had the images, the images of the pawns, king, queen, etc and the board, I could make the image each time... that'll be quite time consuming, but not impossible.

Clough
May 29, 2010, 12:42 AM
Please click on the following link about chess. Images from it would work on this site.

Chess Game for two players. Play online chess free, rules set by game. (http://www.checkers.ws/board_games/chess_games_online/chess_game_two_players/play_chess.htm)

If you click on the board, I think that it gets a lot bigger. However, I'm lacking the proper plugin. Very old machine here...

Most of them were in the Writing or Music forum topic areas. When people want to be able to write music of any kind, I've generally led them to the Writing forum topic area, because I can moderate things there.

A few links about the music writing thing...

Yup, I modified the images so that I can manipulate them more easily. :)

Oh, it's only an image. I can modify the image to suit whatever I want it to be like.

I don't know if you know it, but it's GIMP. Some use photoshop, but I had gimp already on my computer when installed Linux, instead of paint on Windows.

I don't know the first one. I had that on my test and my teacher makes us redo the questions we got wrong. The answer to the second one is 25 cm. The area to a rectangle is A=LW. The area is 125 and the length is 5 times the width. So 125=5w(w)
One of my answer choices was 5 so I just worked backwards. If w=5, then the length is 25 because 5 times 5 is 25. If the width is 5, then 25 times 5 is 125 which is your area. So Your answer is, the length equals 25cm.
