a store is having 20% off sale. the sale price of an item with price “p” is p-0.2p. what is the equivalent expression?

the answer is c)8

step-by-step explanaction:

first, you divide the triangle in two, tô form a retangle triangle. after, using pythagoream theorem:

18^2 = 14^2 + (x/2)^2

(x^2/4) + 196 = 324

x^2/4 = 324 - 196

x^2/4 = 128

x^2 = 512

x = √512

x = √2^9

x = 16√2 cm

i hope i you.
