Factor 6x2−24x−30.(1 point) (6x+1)(x−30)

6(x−1)(x+5)

(6x−5)(x+6)

6(x+1)(x−5)

6(x+1)(x-5)

6x^2-30x+6x-30

6x(x-5)+6(x-5)

(6x+6)(x-5)

6(x+1)(x-5)

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

a = 3.14

b = 18

c = 18/5 or 3.6 or 3 3/5
