f(6) = 0

x = 3 when f(x) = 2

Step-by-step explanation:

f(6) = -2/3(6) + 4

f(6) = -4 + 4

f(6) = 0

2 = -2/3x + 4

-2 = -2/3x

-2x = -6

x = 3

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.
