Alternate interior angles.
The U and inverted U symbols, ∪ and ∩, are mathematical symbols used to denote union or intersection, respectively. For example, when a rational algebraic equation is graphed, there may be some points where the equation is undefined. Visually, we see it as breaks or discontinuities. We use the ∪ symbol to express union. For example, {-∞,2)∪(4,+∞). That means that the graph passes at all x values except x=3.
The ∩ symbol is used for intersection of two lines, for instance. When equation A and equation B are graphed, they can intersect at points (x,y). It is therefore expressed as: A∩B = (x,y).
This question calls for ratios. Reuben drove 268 miles with 12 gallons. 268 divided by 12 is 
, so he can drive 22 and one third of a mile with one gallon. Multiply that by 9 and you will get 201 miles, which is how much he can drive using 9 gallons of gas
