Without plotting these numbers, decide which inequalities are true. Check all that apply. StartRoot 7 EndRoot > 2
StartRoot 7 EndRoot < 7
StartRoot 7 EndRoot < StartRoot 8 EndRoot
StartRoot 8 EndRoot < 2
StartRoot 8 EndRoot < 8

on a coordinate grid, point a is at (−4.0, −2.4) and point b is at (4.0, −2.4). point b is a reflection of point a across the –axis. input either a lowercase x or i think is the right awnser

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
