Answer:
Statement 3
Step-by-step explanation:
<u>Statement 1:</u> For any positive integer n, the square root of n is irrational.
Suppose n = 25 (25 is positive integer), then
![\sqrt{n}=\sqrt{25}=5](https://tex.z-dn.net/?f=%5Csqrt%7Bn%7D%3D%5Csqrt%7B25%7D%3D5)
Since 5 is rational number, this statement is false.
<u>Statement 2:</u> If n is a positive integer, the square root of n is rational.
Suppose n = 8 (8 is positive integer), then
![\sqrt{n}=\sqrt{8}=2\sqrt{2}](https://tex.z-dn.net/?f=%5Csqrt%7Bn%7D%3D%5Csqrt%7B8%7D%3D2%5Csqrt%7B2%7D)
Since
is irrational number, this statement is false.
<u>Statement 3:</u> If n is a positive integer, the square root of n is rational if and only if n is a perfect square.
If n is a positive integer and square root of n is rational, then n is a perfect square.
If n is a positive integer and n is a perfect square, then square root of n is a rational number.
This statement is true.
You write 1/2 is also equal to .5
Answer is a rectangle
paralel and a rectantular prism
the rectangular prism is made up of many recatngles stacked on top of each other
by cutting paralell to the base, you get one of those recatneles
The answer might be 5 times 7 that is 35
