Answer:
Let n be the number
100% of a number is 15 is written as: 100% × n = 15
100% = 100 / 100 = 1
Hence
100% × n = n = 15
We now need to find 50% of the number
50% of 15 = (50 / 100) × 15 = 750 / 100 = 7.5

Answer: 7 feet
Step-by-step explanation:
Since all 4 sides of a square are equal, you do 28 / 4 = 7 feet, which is the answer.
(2n+1)(2n-1)(n+5)
=(4n^2+2n-2n-1)(n+5)
=(4n^2-1)(n+5)
=4n^3-n+20n^2-5
4n^3+20n^2-n-5
