y=5(x - 5)(x+3)

written in vertex form and standard form

Vertex form:

y = 5  (x - 1)^2 - 80

Standard Form:

y = 5x^2 - 10x - 75

1; 35 is the ratio

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
