The answer to this question is D because 16 divided by 8 is 2 and 8 divided by 4 is 2. I hope this helps you :) 

Answer:

d

Step-by-step explanation:

The proportion given to us is

[tex]\frac{16}{x} =\frac{x}{4}[/tex]

Next we cross multiply to get

[tex]16*4=x*x[/tex]

[tex]64=x^2[/tex]

[tex]x^2=64[/tex]

Take the sqrt on both side to get x

so

[tex]\sqrt{x^2}   = \sqrt{64}[/tex]

x=8

so the correct option is d .
