the height of the triangle is 2?

3. anonymous

Okay.

4. anonymous

x/x^2+2x=1/x+1

5. anonymous

Is that the rational expression in simplified form?

6. anonymous

1/(x+2)

7. anonymous

$\frac{ Area of \triangle }{ Area of rectangle }$

8. anonymous

Atriangle=x*2/2=x Arectangle=x*(x+2)=x^2+2x

I'm sorry, I'm still confused, could you help me put all this together so I might understand better? Sorry, if I'm asking too much of you.

To the area of triangle over area of rectangle? No.

12. anonymous

yes

13. anonymous

because it is inside the rectangle

$\frac{ area of \triangle }{ area of rectangle }$ = $\frac{ x(2)/2 }{ x(x+2) } = \frac{ x }{ x^2 + 2x }$
