Correct expression equivalent to 9-(3-6x)

6 + 6x

Step-by-step explanation:

9 - (3-6x) = 9 - 3 - (-6x)

= (9-3) +6x

= 6 + 6x

1) expand the bracket

2) group like terms together

3) simplify to form expression

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
