8 meters
11 meters
17 meters
23 meters
5. Which number is a perfect cube?
7
25
66
27
6. When adding square root of 9 and -7, which type of number is the sum?
Irrational
Whole number
Radical
Integer
7. What is the square root of 36/49
18/25
20/27
6/7
8/9
4. 17 meters
5. 25
6. Whole number
7. 6/7
Am I right?
Scott how does that help?
#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.
someone give us the answers for the love of god

what is 4
Scott 5 is correct
The smart people are saying it's 17 Allison
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.
