Which expressions are polynomials? check all that apply 6 + w z + 1 y^2- 3 square root y + 4 2x^4-y

17 1/3

step-by-step explanation:

can you make your screen more see able?

then i might be able to .

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
