:/ dang I really need help!
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.
@Directrix helps me alot. He is really good. He knows how to explain it right and help you. :)
okay I know how to cross multiply but i dont think im gonna do that right... and thanks @k3nzi14
Go ahead and crank it out. Post your work here and we will check. Be brave.
Your welcome, Even though i couldn't help much.:/
no @Directrix I honestly dont know how to do that one I can set it up but thats about it
@k3nzi14 You can always check the algebra.
huh?
oht that wasnt to me haha
x/(x+5) = (x-2)/(x+1) x(x+1) = (x+5)(x-2)
|dw:1363925466594:dw| so thats what I got so far
@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
thats what im trying to say im not understanding
I know it seems simple but ugh still lost...
I know you can multiply these: x(x+1) = (x+5)(x-2) Do the left side and then do the right side.
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
and im running out of time to finish it so im really frustrated which doesn't help at all
yes its 5x and then there is -2x
right @Directrix ?
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!?
My ping/tag notification does not work on this site. If you are looking for me, send a web mail, I suppose. I asked the Techs to repair that function but so far, no repair.
