1. #5
25 is a perfect square ---- 5^2 = 25 , but
27 is a perfect cube --- 3^3 = 27

#6 is incorrect
√9 - 7
= 3-7
= -4, which is an integer
Whole numbers are positive integers

I agree with the others.

8. Number four explanation:

Formula:
a^2+b^2=c^2

(it doesn't matter which number is in a or b, as long as the bigger number is on c)
8^2+15^2=c^2

8*8....15*15
64+225=c^2

√289=√c^2

17=c

That is how I got 17 as the answer.

Further explained:
The question said, "Mrs. Clarkson designed a *rectangular* garden." The problem also said, "What measure is closest to the length of the *diagonal* walkway?" This basically means that she has a Pythagorean Theorem problem. If you split that rectangle diagonally you get two triangles.

So yes, you are correct for the fourth.
As for everyone else with not knowing the explanation, I hope that helped.
