Answer:
the slope of the line is -2
Jen's car because if you divide 140 by 5 you get 28 and that's 28 miles per gallon. When you divide 300 by 12 you get 25 and that's 25 miles per gallon.
The sum of the interior angles of the polygon = (n - 2) x 180 .
(n - 2) x 180 = (n x 150)
180n - 360 = 150n
Add 360 to each side:
180n = 150n + 360
Subtract 150n from each side:
30n = 360
Divide each side by 30 :
<u>n = 12</u>
