X^2 - 4x + 24 trinomial factor

true? is that what you're asking or do you mean something else?

the square root of what number? if you add that, then someone will probably answer the question.

the answer is b: 18

step-by-step explanation:

use the pythagorean theorem to .

a^2+b^2=c^2

plug 18 for "r"

the 2 legs are 18 and 24

18^2+24^2=c^2

324+576=c^2

900=c^2

c=30

30-12=18

18 is the radius
