The slope of x-y=8 is 1 because it's actually y = x-8
Parallel means the slope is equal to 1 as well.
That's a <em>rhombus</em>. If it has one interior right angle, then
it's a special case of rhombus known as a "square".
Set the height to h, and the width to w.
We know that wh=190 and h=2w-1.
Substituting 2w-1 for h, we have:
w(2w-1)=190
So:
2w^2-w-190=0
Factoring this equation, we get (2w+19)(w-10)=0. The solutions to this equation are -9.5 and 10, but clearly the width must be positive, Substituting 10 for the width, we get 10*2-1=19 for the height.
