Answer:
y=-13x + 78 I'm not sure what's up with those answer choices though

Data:
d=6343miles
t=9h

Then, the plane traveled at a speed of 704.77 miles per hour.
Ive never seen a question lie this before
Since the first figure is a square I guess it stand for x^2
then we have -2x + 3x = x ( the 2 stets of rectangles)
and finally -3 + 1 = - 2
So i am presuming its x^2 + x - 2
Option b
Im not sure though
