Respuesta :

It is w because once you take the square root of the number you will see it is about 5.477 so you know that it will be closer to 5.4 because there is a two in front of the 7's.

I hope this helped :)
The root of 30 = 5.47 which if rounded = 5.5

so you are more closer to x than to w

so your answer is x
