You can square both sides, to start with.
 one year ago

joshiBest ResponseYou've already chosen the best response.0
oh do you just need x by itself? i thought you wanted like actual values. ok phew
 one year ago

scarydoorBest ResponseYou've already chosen the best response.0
getting x by itself is getting the actual values.
 one year ago

joshiBest ResponseYou've already chosen the best response.0
no i meant like a numerical value
 one year ago

scarydoorBest ResponseYou've already chosen the best response.0
it would be a numerical value. Determined by unknown d and variable y.
 one year ago

mercediesBest ResponseYou've already chosen the best response.0
i have know idea what to do
 one year ago

joshiBest ResponseYou've already chosen the best response.0
did you square both sides?
 one year ago

joshiBest ResponseYou've already chosen the best response.0
what do you mean? well i got 4xy=9d^2
 one year ago

mercediesBest ResponseYou've already chosen the best response.0
\[\sqrt{4xy}=3d\]ummm
 one year ago

mercediesBest ResponseYou've already chosen the best response.0
i need to solve for x
 one year ago

joshiBest ResponseYou've already chosen the best response.0
well squaring both sides would get you (squareroot 4xy) ^2 = (3d)^2
 one year ago

joshiBest ResponseYou've already chosen the best response.0
and so now you're squaring a square root. it's like (squareroot of 4)^2 square root of 4 is 2 right? so it would be 2^2 which is 4 again. so basically if you're squaring a square root, you're not really doing anything so the square root and square cancel each other out if that makes sense
 one year ago

joshiBest ResponseYou've already chosen the best response.0
so you get how to square both sides then?
 one year ago

mercediesBest ResponseYou've already chosen the best response.0
idk this is my first time doing this or a problem like this
 one year ago

joshiBest ResponseYou've already chosen the best response.0
oh ok well have you done questions like this: x^2 = 25
 one year ago

joshiBest ResponseYou've already chosen the best response.0
yeah this question is pretty much the same thing
 one year ago

joshiBest ResponseYou've already chosen the best response.0
so in the x^2=25 you basically square rooted both sides. so square root of x^2 = square root of 25 x=5 but it in this question you have to square both sides, give it another try
 one year ago

mercediesBest ResponseYou've already chosen the best response.0
so you square the 3d
 one year ago

joshiBest ResponseYou've already chosen the best response.0
yup and also the sqrt 4xy
 one year ago

mercediesBest ResponseYou've already chosen the best response.0
kk then what do i do
 one year ago

joshiBest ResponseYou've already chosen the best response.0
did you also square the other side?
 one year ago

mercediesBest ResponseYou've already chosen the best response.0
so would it be 16xy^2
 one year ago

joshiBest ResponseYou've already chosen the best response.0
no because remember its squareroot of 4xy already. so squaring it gets you squareroot of 4xy times squareroot of 4xy which is just 4xy
 one year ago

mercediesBest ResponseYou've already chosen the best response.0
so it stays the same
 one year ago

joshiBest ResponseYou've already chosen the best response.0
can you solve it now? you just have to get x by itself
 one year ago

mercediesBest ResponseYou've already chosen the best response.0
would the square roots still be there
 one year ago

mercediesBest ResponseYou've already chosen the best response.0
so it would look like 4xy=9d
 one year ago

joshiBest ResponseYou've already chosen the best response.0
ok well you should also probably ask your teacher this too cause in math it's really important to know why things happen
 one year ago

mercediesBest ResponseYou've already chosen the best response.0
kk i dont have a teacher
 one year ago

joshiBest ResponseYou've already chosen the best response.0
oh...how does that work?
 one year ago

mercediesBest ResponseYou've already chosen the best response.0
well my mom is my teacher but my mom is in the hospital
 one year ago

mercediesBest ResponseYou've already chosen the best response.0
how do i get x by it's self
 one year ago

joshiBest ResponseYou've already chosen the best response.0
sorry if you dont mind me asking, what grade are you in? like technically, like your age
 one year ago

joshiBest ResponseYou've already chosen the best response.0
so in an equation whatever you do to one side, you have to do to another. so you could add y to both sides which would get you 4x by itself
 one year ago

joshiBest ResponseYou've already chosen the best response.0
sorry again, (none of my business i know) but why don't you go to school?
 one year ago

mercediesBest ResponseYou've already chosen the best response.0
so what i got was 4x=9dy drama and lot of fighting
 one year ago

joshiBest ResponseYou've already chosen the best response.0
that's right except that it's d^2 not just d
 one year ago

joshiBest ResponseYou've already chosen the best response.0
oh, well i'm sorry. hope it works out, whatever it is
 one year ago

mercediesBest ResponseYou've already chosen the best response.0
thank you well we are having hard times my bf just got put in jail for a year
 one year ago

joshiBest ResponseYou've already chosen the best response.0
aww :/ Imagine all the people, living life in peace... *swaying to the awesome music* sorry, only thing i could think of
 one year ago

joshiBest ResponseYou've already chosen the best response.0
It's good that you're doing math and stuff though
 one year ago

mercediesBest ResponseYou've already chosen the best response.0
lol thank you hes only 15
 one year ago

joshiBest ResponseYou've already chosen the best response.0
i thought you couldn't go to jail unless you're an adult? well i suppose different countries
 one year ago

mercediesBest ResponseYou've already chosen the best response.0
ya well i live in hawaii so there is only two jails and one prison and a whole lot of bad kids they do what they have to
 one year ago

joshiBest ResponseYou've already chosen the best response.0
ohh the kids do what they have to?
 one year ago

mercediesBest ResponseYou've already chosen the best response.0
ya well know that i look back at what happened it is his own problem
 one year ago

joshiBest ResponseYou've already chosen the best response.0
oh. well anyways good luck. time heals
 one year ago

mercediesBest ResponseYou've already chosen the best response.0
ya kk so know what do i do with 4x=9d^2y
 one year ago

joshiBest ResponseYou've already chosen the best response.0
oh i thought you'd solved it. well think about, this time entire time you've been doing things to both sides. how would you get x by itself this time?
 one year ago

mercediesBest ResponseYou've already chosen the best response.0
you divide 4 on both sides
 one year ago

mercediesBest ResponseYou've already chosen the best response.0
because what happens on one side you do to the other
 one year ago

joshiBest ResponseYou've already chosen the best response.0
yeah! exactly! :D good job
 one year ago

mercediesBest ResponseYou've already chosen the best response.0
thank you so it would be 2.25 d^2y
 one year ago

joshiBest ResponseYou've already chosen the best response.0
wait what? so i had 4x=9d^2 + y and so x= (9d^2 + y)/4
 one year ago

mercediesBest ResponseYou've already chosen the best response.0
ya and that is what i did then i divided 9/4=2.25
