If a = (0, 0) and b = (8, 2), what is the length of ab?

what is the answer to this

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.

step-by-step explanation:

no solution.

step by step explanation: when u removing the parentheses and combined them that would be : x+3y-x-y=2y
