Three expressions that are equal to 5/9 x 8

They all equal because they all give

Step-by-step explanation:

They all equal because they all give

Done by writing three equations with one random number and the desired result, , returning the answers above.

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
