Answer: A

Step-by-step explanation:

This is because 25%= 25/100, and that reduces to 1/4. Also, whenever it says something OF something, it means to multiply. In this case, 1/4 OF 1000= 1/4x1000= 250.

*Even though it seems that multiplying will just make the number bigger, when you multiply with a fraction, it actually gets smaller* For example 1/3 of 3= 1/3x3= 1

Inga [223]

Answer:

$4\sqrt{6}+16$

Step-by-step explanation:

Given the expression: $4\sqrt{6}+8\sqrt{4}$

$\sqrt{4}=2\\$Therefore, \\4\sqrt{6}+8\sqrt{4} =4\sqrt{6}+8*2\\ =16+4\sqrt{6}$

We can re-write the answer as:

$4\sqrt{6}+16$

The answer is irrational because the sum of a rational number and irrational number is an irrational number.
