Question

I made an equation and I know the equation will work for it but I need to find out what x equals.
500=[2pi(x/2)]2+x

unklerhaukus · Answer

$$500=\big[2\pi(x/2)\big]^2+x$$

anonymous · Answer

Oops my bad hold on i'll write it correctly.

anonymous · Answer

$$500=[2\pi(x/2)]2+x$$

anonymous · Answer

so it's times 2 not to the power of 2

unklerhaukus · Answer

oh
$$500=\big[2\pi(x/2)\big]\times2+x$$

anonymous · Answer

not sure what to do after I divide both sides by 2

anonymous · Answer

Yup

unklerhaukus · Answer

lets look at this bit first 

$$[2π(x/2)]× 2$$, can you simplify this

anonymous · Answer

not sure what I did was I divided both sides by 2 to get rid of the 2 but I don't think that was right

anonymous · Answer

$$4\pi(x/2)$$

unklerhaukus · Answer

Yes, $$[2π(x/2)]×2=4\pi (x/2)$$
now, simplify again
$$=$$

unklerhaukus · Answer

(combine the 4 and the /2 )

anonymous · Answer

$$2pix$$

unklerhaukus · Answer

yeah so you have 
$$500=\big[2\pi(x/2)\big]\times2+x\
500= 2\pi x+x$$

unklerhaukus · Answer

now can you see a common factor in the right hand side ?

anonymous · Answer

Oh ok that makes sense I got ti from here thanks a bunch!
