True or false? When we simplify a radicand that is negative… the first step is to separate the “imaginary unit” from the rest of the radicand.

depending on others is critical to survival. my source is apex!

step-by-step explanation:

i think it might be a but you might want a second opinion

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.

he answer is x=1x3 because x=1 to x=3
