If the perimeter is 26, and the width is 4, then add 4 twice, to get 8. Then subtract 8 from 26 to then get 18, you have two lengths, so divide 18 by 2. Your answer is 9.
To check add 4+4+9+9 = 26.
hope it helped! :)
Answer: 7.07 so 7.1
Step-by-step explanation:
Squares have 4 equal sides which puts each side at being 5. Then to find the diagonal you use sqrt(2)a so the square root of 2 times a which is 5 in this case.

Answer:
598 books
Step-by-step explanation:
Let x be the number of books in the 3rd pile. We will have then:
1st pile: 2x + 10
2nd pile: 2x
3rd pile: x
3000 = (2x + 10) + (2x) + (x)
3000 = 5x + 10
3000 - 10 = 5x
2990 = 5x
2990/5 = x
x = 598 books in the third pile!
We can check that:
3000 = 2*598 + 10 + 2*598 + 598
3000 = 1196 + 10 + 1196 + 598
3000 = 3000 CHECK!
