Reducing chocolate bar dimensions and finding k in quadratic equations

[RubyRed]

there is no where to put pharentheses on the windows calc

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! yay I almost got it. lol I can't believe you have spent so much time online helping me with something so tedious! I appreciate it so much though...now let's see if I can get it this time...

hehe no problem I am just watching television

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

 

[bob1182006]

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?

 

[RubyRed]

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
