Solve the three equations in the table using any method of your choice. List the method you used. Equation Solutions Method Used x2 − 4 = -12 -9x2 + 4x − 10 = 0 x2 + 8x = -17

there is no grid

step-by-step explanation:

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

: )

d 600 because 15*10*2=300

300+300=600
