Best ResponseYou've already chosen the best response.0Good work, unfortunately some algebra mistakes. When working on an equation, If you do something to one side, you have to do to the other side (all terms). Likewise when you do something to a radical expression p/q; you must do top and bottom.

Best ResponseYou've already chosen the best response.0ahh i see so then that would make it x = 400*666.7?

Best ResponseYou've already chosen the best response.0On your first step you square, square root (400 + x^2) and 1000 but you didn't square 1500. In any event, it is not recommended to go this route. When you want to square to remove radical, you should first isolate the radical to one side and all other terms to the other side. So your first step, it is recommended to multiply through by sq rt (400+x^2) not to remove radical but to cancel it from the denominator.

Best ResponseYou've already chosen the best response.0That was a big jump from one step to the next, may be it's right but the next step is \[1000(\sqrt{400+x ^{2}}) +1500x=0\]

Best ResponseYou've already chosen the best response.0is the next step moving the "1000" over the "=" sign making it a positive?

Best ResponseYou've already chosen the best response.0You can, but it is just as easy to divide by 1000.

Best ResponseYou've already chosen the best response.0so it just basically cancels out?

Best ResponseYou've already chosen the best response.0\[\sqrt{400+x ^{2}}=(1500x)/(1000)\]

Best ResponseYou've already chosen the best response.0wouldnt it be positive 1000?

Best ResponseYou've already chosen the best response.0would it be 1500x=\[\sqrt{400+x ^{2}}\](1000) ?

Best ResponseYou've already chosen the best response.0The purpose of doing this is to isolate the radical, then square it and get rid of it\[400+x ^{2}=(9x ^{2})/4\]

Best ResponseYou've already chosen the best response.0how did you get \[(9x ^{2})/4??\]

anonymous

Best ResponseYou've already chosen the best response.0\[[(1500x)/(1000)]^{2}=(15x/10)^{2}=(3x/2)^{2}\]

Best ResponseYou've already chosen the best response.0I am not confident in your work, you jump too many steps; it's not the way you do mathematics. Work it from there. I'll check it later. It is definitely not 31

Best ResponseYou've already chosen the best response.0okay i went from your step to \[x^{2}=(9^{x ^{2}}400]??

anonymous

Best ResponseYou've already chosen the best response.0ahhh i had \[\sqrt{200}\] .... boy was i off ... well thank you so much for helping me i have a better understanding for calculus im in 10th grade so im new to this ... you were tons of help ..bye bye?!

Best ResponseYou've already chosen the best response.0Good work, you are doing good. It took years of working with a tutor for me to feel this comfortable.
