Step-by-step explanation:This is what i got.
the perimeter of the kite:
20+20+33+33=106mm
It would have a variable, and/or coefficients and sometimes constants
You can find the remainder right away by simply plugging in

. The polynomial remainder theorem guarantees that the value of

is the remainder upon dividing

by

, but I digress...
Synthetic division yields
3 | 2 -11 18 -15
. | 6 -15 9
- - - - - - - - - - - - - - - - -
. | 2 -5 3 -6
which translates to

(and note that

, as expected)
