Simplify each radical expression, if possible 3v/7-5^4v/7

Acamper leaves camp on a kayak and travels 50 miles east on a river, then he ties his kayak to the bank and travels 20 miles north on a bicycle. this trip can be plotted on the coordinate plane, where the camp is the point (0, 0). the distant of the camper to the camp can be found using the distance formula. which other formula can he use? a) 502 - 202 b) 502 + 202 c) 502 - 202 d) 502 + 202

Can someone answer it, and plot it, for 20 points and brainliest answer? p.s. they're the same ! : )
