Two trains, train A and train B, weigh a total of 485 tons. Train A is heavier than train B. The difference of their weights is 303 tons. What is the weight of each train

80x^8−68x^6+16^5−20x^4−4x^3+8x^2

hope i'm right lol

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
