Given: f(x) = 3x 2 + 1, g(x) = 2x - 3, h(x) = x f(x) + g(x) =
a.3x 2 + 2x - 2

b.5x 3 - 2

c.3x 2 + 2x + 4

the correct is answer is a 9-sided polygon!

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

113.42

i hope that is right.
