## ValentinaT 2 years ago Help with geometry/rational expressions?

1. ValentinaT

2. SerikMB

the height of the triangle is 2?

3. ValentinaT

Okay.

4. SerikMB

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

5. ValentinaT

Is that the rational expression in simplified form?

6. SerikMB

1/(x+2)

7. SerikMB

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

8. SerikMB

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

9. ValentinaT

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.

10. SerikMB

11. ValentinaT

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

12. SerikMB

yes

13. SerikMB

because it is inside the rectangle

14. ValentinaT

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