c. 16
d 8

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 2

d

Explanation:

The proportion given to us is

`(16)/(x) =(x)/(4)`

Next we cross multiply to get

`16*4=x*x`

`64=x^2`

`x^2=64`

Take the sqrt on both side to get x

so

`√(x^2)   = √(64)`

x=8

so the correct option is d .
