Which of the following is equivalent to 5x+2/x = -12/x-1

a) 6x - 1 = -12x

b) - 12(5x + 2) = x(x-1)

c) - 12(x - 1) = x(5x + 2)

d) (5x + 2) (x - 1) = -12

For this case we must find an expression equivalent to:

We multiply both sides of the equation by "x":

We multiply both sides of the equation by "x-1":

step-by-step explanation:

given that there are two triangles j'k'l' and jkl>

the former is got by dilating the second one.

when drawn on a grid, (graph paper) coordinates of vertices of first triangle is

(6,12)j, (9,6)k and (12,9)l

side jk has length = distance between j and k

=

side j'k'=distance between j' and k'

=

ie j'k'l' has sides 1/3 of that of corresponding sides of jkl.

hence scale factor of 1/3 is used to get j'k'l'from jkl
