Which answer choice shows 727,000 correctly written in expanded form? a.700,000 + 20,000 + 7,000 b.70,000 + 2,000 + 700 c.70,000 + 2,000 + 7,000 d.700,000 + 20,000 + 700

A. becuase you just follow thw number place ment and add zeros. so the firt 7 has five places behind it you jut put zeros in those plases.

your anwser would be A . i hope this helped!

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
