Gasoline costs 1.77 euro per liter in France. What is the price in dollars per gallon?

so mark-up is 0.4 multiplied by 180 = 72

the diagram shows you   triangle def with de=4, df=9 and de≠df≠ef.

the sum of the lengths of two triangles' sides are always greater than the length of the third side:

substitute sides lengths:

then 5< ef< 13 (option 3 is true).

def is a scalene triangle with all sides of different lengths (option 5 is true, option 2 is false).

answer: correct choices are 1, 3 and 5

the first is 13 the second is 1 the third is 8 and the fourth is 7
