multiply both sides by x and tell me what you get
OpenStudy (anonymous):
you mean 3x32?
OpenStudy (anonymous):
or x*x= x squared?
OpenStudy (zzr0ck3r):
we have \[\frac{ 3 }{ x }\] = \[\frac{x}{32}\]
OpenStudy (anonymous):
yes

OpenStudy (zzr0ck3r):
so multiply both sides by x and we have
3 = x^2/32 right?
OpenStudy (anonymous):
yes but what about the 3?
OpenStudy (zzr0ck3r):
now muliply both sides by 32
now we have
32*3 = x^2
right?
OpenStudy (anonymous):
yes.

OpenStudy (zzr0ck3r):
ok so now we have x^2 = 96
can you solve for x?
OpenStudy (zzr0ck3r):
note: sqrt(96) = sqrt(16*6) = sqrt(16)*sqrt(6) = ?

@meylispena we are not here to give answers, please let them participate.
its not right also
OpenStudy (anonymous):
I deleted it, I'm sorry for the inconvenience.
OpenStudy (anonymous):
is the answer \[4\sqrt{6}\] ?

so sqrt(16)*sqrt(6) = +- 4*sqrt(6)
OpenStudy (zzr0ck3r):
there are two answers....
