Bananas cost $0.54 per pound and grapes cost $1.28 per pound. leanne bought 2.6 pounds of bananas and 3.1 pounds of grapes. how much did she pay for the bananas and grapes she bought? show your work.

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.
