This arithmetic sequence - 11;-4;3forms the first three first differences of a quadratic sequence. Which term in this quadratic sequence will be the smallest. Show all calculations​

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.

just sum

10 + 10 = 20
