Simplify:
k-10k+1 +
1
5k-2k-3
k-1

I couldn't quite understand the problem, but if the problem was k-10k+1+15k-2k-3k-1 the answer would be k

Step-by-step explanation:

it would be k because k-10k+1+15k-2k-3k-1. Then subtract 10k from from k so you get -9k+15k-2k-3k. then add -9k and 15k getting you 6k-2k-3k. Then subtract 2k from 6k giving you 4k-3k. Then subtract 3k from 4k giving u 1k which would be just k.

the answer is 99.

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
