3(x - 2)(x - 5)

Step-by-step explanation:

Factor 3 from all terms within the trinomial:

(3x² - 21x + 30)/3 = x² - 7x + 10

3(x² - 7x + 10)

Simplify.

(x² - 7x + 10)

x               -5

x               -2

3(x - 2)(x - 5)* is your answer.

* remember to bring the 3 that you factored out in the beginning and stick it to the front.

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.
