The three sides of a triangle are n. 4n + 1. and 4n - 2. If the perimeter of the triangle is 71 feet, what is the length of each side

8

Step-by-step explanation:

n+(4n+1)+(4n-2) = 71

n+4n+1+4n-2= 71

   9n-1=71

    9n= 72

      n=8

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
