length, l width, w
perimeter, p = 2(l+w)...eqn 1
l = w -16...eqn 2
subst for l in eqn 2 into eqn 1...
p = 2((w-16) + w)
p = 4w -32
using p = 96, 96 = 4w -32, w = 32 inches
l = w- 16 = 16inches
1. Write the factors
(x+3)(x-6) = 0
2. Multiply the factors to get the answer in standard form
x^2 + 3x - 6x - 18 = 0
3. Simplify
x^2 - 3x - 18 = 0

Actually Welcome to the Concept of the mirror reflection.
Since the image of triangle is reflected along Y-axis,hence the coordinates of N after 270° rotation are
N ==> ( 3,0)
===> Option D.) is correct
