What is the answer -12c-4+7.5c-11=-6

Step-by-step explanation:

Combine like terms:

-4.5c -4 - 11 = -6

-4.5c - 15 = -6

Add 15 to both sides:

-15 + 15    =    -6 + 15

0                   9

-4.5c = 9

Divide both sides by -4.5:

c = -2

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
