Homework Help Overview

The discussion revolves around various algebraic problems, including volume calculations and quadratic equations. The original poster seeks assistance with a problem involving the dimensions of a chocolate bar and another regarding the conditions for a quadratic equation to have a repeated solution.

Discussion Character

  • Mixed

Approaches and Questions Raised

  • Participants explore the volume reduction of a chocolate bar, questioning how to maintain the relationship between length and width while reducing dimensions. They also discuss the conditions for a quadratic equation to have a repeated solution, with some participants attempting to clarify the implications of this condition.

Discussion Status

There is an ongoing exploration of the problems, with participants providing hints and guidance without reaching a consensus. Some participants have made progress on the chocolate bar problem and are attempting to solve the quadratic equation, while others express confusion about specific steps and concepts.

Contextual Notes

Participants note the constraints of the homework context, including the requirement to reduce the volume by a specific percentage and the conditions for the quadratic equation. There is also mention of the need for clarity on mathematical definitions and procedures.

yes that's right, now plug both of the numbers into the 12-x, 7-x and if you get a negative number then that's not the solution you need

ok so l=11.07 and w=6.07 :) When rounded

ok so for the first one I got 18.07029 so on and so on and for the second one I got
0.929702 so on and so on...is that right?

if you got that then how could you get 11.7 and 6.7?
 
  • #37
when I take the l=12-.93 which means that l= 11.07 and the width would be 7-.93 which is the 6.7
I could already tell the 18.07 wouldn't work because it would be a negative number when subtracted from the 12 and 7.

ooooo hehe sorry thought you meant 11.7 not 11.07 >.< but yea that's the answer :) hehe took a while to solve it

GOSH it took FOREVER! But I got it! yay! haha thanks so much for your help, I am sure I will be on this forum often, so maybe I will put you through math hell and help me again sometime. lol But for now I have had ENOUGH math, ugh, thanks again. Talk to you later! G'Night
