Max paid $45 for 15 gallons of gasoline, sarah paid $47 for 20 gallons of gasoline. who bought gas at a cheaper price per gallon? question 4 options: sarah or max

In order to answer the question, you have to compute the unit price: max paid 45$ for 15 gallons, so he paid each gallon

On the other hans, Sarah paid each gallon

last option

step-by-step explanation:

given that δdef is right and isoceles,

assuming that side df is the hypotenuse means that de an ef are the other 2 sides that intersect at 90° and are of equal length.

because they are of equal length, we can say that they are congruent

because they intersect at 90°, their slopes must be opposite reciprocals.

only the last option satisfies these conditions.
