Answer:
6/3
Step-by-step explanation:
6/3 is equal to 2 its bigger than any other number
2n + 1 et 2n + 3 are two odd integers with n integer
(2n+1)(2n+3) = 4n² + 8n + 3 =2(4n² + 4n) + 3
2(4n² + 4n) is an even integer so 2(4n² + 4n) + 3 is an odd number
because the sum of an even number and an odd number is an odd number.
To get from one even number to the next even number you have to add 2.
Ex. 4, 6, 8. If I start with 4, I have to add 2 to 4 to get to 6, and add 4 to 4 to get to 8. Since we don't know the starting point in this word problem we start with'x' and add 2 and add 4.
x = (x + 2) + (x + 4)
x = 2x + 6
The first equation
