If c(x) = 4x – 2 and d(x) = x2 + 5x, what is (cd)(x)? 4x3 + 18x? – 10x
x² +9x-2
16x2 + 4x - 6
4x2 + 20x - 2

the diver is 33 feet below the surface.

step-by-step explanation:

hope 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
