Write an expression showing the sum of 8 and a number of f

w'x is 0.

hope it

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.

the answer to this would be 5x^3-6x^2-24 over 3x^2

hope this if needed hmu
