16. rewrite the given functions in vertex form,
k(x) = x2 - 16x + 2
18. rewrite the given functions in vertex
form, f(x) = (2x - 3)(x + 4)
20. solve the system of equations
x + 2y = 4
x - y =2

the answer is 62

18.75 gallons

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
