Write the equation of the giving circle center (-2,-2) radius of 6

(x+2)²+(y+2)²=36

Step-by-step explanation:

given r=6

center is (-2,-2)

the equation becomes

(x-(-2))²+(y-(-2))² = 6²

on simplifying we get the answer

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
