5. Select the correct inequality for the graph below: O y < 3x - 1
O y S 3x - 1
O y 2 3x - 1
O y > 3x - 1

do i do it on a graph?

step-by-step explanation:

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.
