22 + 32 = 13
When the sum of a number plus 3 is squared, it is 11 more than the sum of the number plus 2 when squared.
An algebraic expression representing the sum of a number squared and 2 can be written as ( x^2 + 2 ), where ( x ) is the variable representing the number. In this expression, ( x^2 ) indicates the number squared, and adding 2 accounts for the additional term.

It cannot be. If 47 is the sum of two prime numbers, one must be an even number and one must be an odd number, because that is the only way to have a sum that is an odd number, such as 47. The only even prime number is 2. The number that with 2 will have a sum of 47 is 45. However, 45 is not a prime number. Therefore, there are not two prime numbers that have a sum of 47.
