A rectangular parking lot has a length of 84 feet and a width of 56 feet. Which of the following could be used to find the diagonal distance across the parking lot? 842−562=c2
84 squared minus 56 squared is equal to c squared

842+b2=562
84 squared plus b squared is equal to 56 squared

(84+56)2=c2
open paren 84 plus 56 close paren squared is equal to c squared

842+562=c2

they are simplified

step-by-step explanation:

3.how is solving radical equations different than solving linear equations?

step-by-step explanation:

cant open file sorry!

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
