Aheptagon has one side that is 16x2 + x - 17 units in length,
another side that is 2x2 – 9x – 14 units in length, and two sides that are each
4x2 -- 5x + 3 units long. if each of this heptagon's remaining sides has a
length of 11x2 - 2x + 9 units, what simplified expression represents the
perimeter of this heptagon?
the perimeter of the heptagon is ?
