@YanaSidlinskiy are the ones in the bottom the choices?

yanasidlinskiy · Answer

no its 5x +10/ x+2 multiply by 2x/4x-10

Have you studied Order of Operations?  It may also be called "Precedence".

yanasidlinskiy · Answer

yeah...but i still can't figure it out...im like really stuck..

Then you should review that material.  It will help A LOT to write clearly what you mean.

 5x +10/ x+2 means $5x + \dfrac{10}{x} + 2$

2x/4x-10 means $\dfrac{2x}{4x} - 10$ or maybe $\dfrac{2x}{4}x - 10$

If you mean NONE of that, please use parentheses to clarify meaning.  I suppose you may have meant:

$\dfrac{5x+10}{x+2}\cdot \dfrac{2x}{4x-10}$

Factor what there is to be factored.

$\dfrac{5(x+2)}{x+2}\cdot \dfrac{2x}{2(2x-5)}$

Rearrange a bit.

$5\cdot\dfrac{x+2}{x+2}\cdot\dfrac{2}{2}\cdot\dfrac{x}{2x-5}$

Simplify where you can.

$5\cdot\dfrac{x}{2x-5} = \dfrac{5x}{2x-5}$

Seriously, try to use proper notation.  It WILL save you!

Is the answer gonna be like $$\frac{ 10x+10 }{ 4x + 20}$$

tkhunny · Answer

Maybe something like that, but there is more to do.
