Answer:
(6y - 1)(6y + 1)
Step-by-step explanation:
To factorize completely, we may adopt the difference of 2 squares approach. The theory states that difference of two square is the product of the difference of the number and the sum of the numbers.
Such that
a² - b² = (a - b) (a + b)
Hence 36y² - 1
= 6²y² - 1²
= (6y)² - 1²
= (6y - 1)(6y + 1)
22 rides would be needed Explanation: one ride takes 6 kids and there are 130 kids 20 rides would take 120 21 rides would take 126 and since you can’t have kids without a ride and you can’t cut a ride into pieces there must be 22 rides
