First simplify the number part, 14/2 = 7/1
then the x part,
y doesn't need to be simplified
then simplify the z part, z^-6 = z^6
put it all together...
2* 100 + 2 * 65 = 330 perimeter
100 * 65 = 6,500 area
2*90 + 2*75 = 330 perimeter
90 * 75 = 6,750 area
keep in mind that, a negative coefficient to "x", will make the graph reflect over the y-axis.
