10.2=x^2*√3/4 solve for x

Question

anonymous · Answer

see this e.g.
ques. x+3/ x-2 + 2 = x+5/x-2
answer.. Multiply each term by the LCD of x-2 thus producing

x+3 +2(x-2)=x+5
x+3+2x-4=x+5
3x-1=x+5
2x= 6
x=3

it q=will help u a lot! :)

10.2 = 3x^2√4
10.2/√4 = 3x^2
10.2/3√4 = x^2
±√(10.2/3√4) = x

let me get this straight...

10.2 = (x^2)(\[3 sqrt 4) right?

lgbasallote · Answer

or is it cube root 4?

anonymous · Answer

it is the formula to find the area of a equalatrial triangle.

anonymous · Answer

@Rohangrr check your answer again. It comes out with x^2*3√4=54

anonymous · Answer

Sorry, I see it was an example

anonymous · Answer

@psujono  don't do shanky! it's an EXAMPLE

anonymous · Answer

$$x=\pm \sqrt{\frac{10.2}{3\sqrt{4}}}$$

anonymous · Answer

No. wrong again (didn't read question properly)

anonymous · Answer

basically the 10.2m^2 is the area of an equalatiral trinagle and the original question was the find the lenth of the sides.

lgbasallote · Answer

did  it come out $$x = 2\sqrt{\frac {10.2}{\sqrt{3}}}$$ 

because that would make sense...

lgbasallote · Answer

wait...i see it can still be simplified...

$$x = 2\sqrt{3.4\sqrt{3} }$$

right?

anonymous · Answer

strangely my text gives the answer 4.85m

lgbasallote · Answer

yuppp if you use calculator..you get 4.85...i used wolfram alpha and this came out http://www.wolframalpha.com/input/?i=2+sqrt+%283.4+sqrt+%283%29+%29
