9th

5. k3nzi14

okay i cant help. im a grade below... 8th im really sorry.

6. UmmmHELP

:/ dang I really need help!

7. Directrix

If a line is parallel to one side of a triangle and intersects the other two, then it divides them proportionally. So, x is to (x + 5) as (x - 2) is to (x + 1) x/(x+5) = (x-2)/(x+1) Cross multiply and solve for x.

8. k3nzi14

@Directrix helps me alot. He is really good. He knows how to explain it right and help you. :)

9. UmmmHELP

okay I know how to cross multiply but i dont think im gonna do that right... and thanks @k3nzi14

10. Directrix

Go ahead and crank it out. Post your work here and we will check. Be brave.

11. k3nzi14

Your welcome, Even though i couldn't help much.:/

12. UmmmHELP

no @Directrix I honestly dont know how to do that one I can set it up but thats about it

13. Directrix

@k3nzi14 You can always check the algebra.

14. UmmmHELP

huh?

15. UmmmHELP

oht that wasnt to me haha

16. Directrix

x/(x+5) = (x-2)/(x+1) x(x+1) = (x+5)(x-2)

17. UmmmHELP

|dw:1363925466594:dw| so thats what I got so far

18. UmmmHELP

@Directrix

19. k3nzi14

@Directrix true. but i just haven't learned that subject yet. .. and @UmmmHELP cross multiply the x+1 with the x.. and then cross multiply the x+5 with the x-2

20. UmmmHELP

thats what im trying to say im not understanding

21. UmmmHELP

I know it seems simple but ugh still lost...

22. Directrix

I know you can multiply these: x(x+1) = (x+5)(x-2) Do the left side and then do the right side.

23. UmmmHELP

okay well x+5 is just 5x isnt it? like no im not trying to play dumb or anything I honestly 100% dont know what to do this is really confusing to me

24. UmmmHELP

and im running out of time to finish it so im really frustrated which doesn't help at all

25. k3nzi14

yes its 5x and then there is -2x

26. k3nzi14

right @Directrix ?

27. UmmmHELP

okay guys seriously Im running out of time and no I dont want the answers and I know im not understanding this even though your explaining but could someone please try and explain it some more or a different way!?

28. Directrix
