Let x = a bi and y = c di and z = f gi. Which statements are true? Check all of the boxes that apply. X y = y x (x Ă— y) Ă— z = x Ă— (y Ă— z) x â€"" y = y â€"" x (x y) z = x (y z) (x â€"" y) â€"" z = x â€"" (y â€"" z).

i am thinking c. sorry if im wrong .

step-by-step explanation:

f(x) = x^3 -2x^2 -3x

x( x^2 -2x-3)

x( x^2 +x -3x -3)

x( x(x+1) -3(x+1))

x( x-3)( x+1)

so zeroes are 0, 3,-1

its (2) option

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

any options?
