sturdy jacinth Whats x The “4” and “x” lines r parallel

As the lines are parallel, the triangles are similar. Then, the ratio of respective sides must be the same:
x/4 = 6/(6 + x)
So, now you can find x.

why cant u do it like 6/x = (6+x)4

#

I tried that but it didnt work

#

Well, what did you get?

sturdy jacinth Jun 17, 2023, 10:45 AM

#

X=12-6*(the square root of x)🗿

#

Uh, can you show the process?

#

Huh. Sorry, but that seems like complete nonsense.
x/4 = 6/(x + 6)
First, we cross-multiply and simplify.
x(x + 6) = 24
x^2 + 6x - 24 = 0
This is a quadratic equation, so solve it as usual.

Wait

#

Not to be annoying but the correct answer is apparently this (210)

#

#

Yes, that is what you get when you solve it.
