Three posters cost $9.60. at that rate, how many posters can you buy for $48?

3 posters = $9.60

 x posters = $48

Let x be the number of posters

$48*3/9.60

144/9.60

x= 15

I hope that's help !

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.
