Evaluate each expression for r= -3 and s= 5. 3r/ s-2

-3

Step-by-step explanation:

replace the letters with the number, 3(-3) / (5)-2

evaluate, -9 / 3

divide, -3

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.

-14 is the answer

hope this : ))
