Help help help

f(1) = 6

Step-by-step explanation:

Step 1: Define

f(x) = 6x

f(1) is x = 1

Step 2: Substitute and Evaluate

f(1) = 6(1)

f(1) = 6

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.
