Is 2x plus 2 even integer?
Only if x is already an integer. For any integer x, 2x + 2 will be an even integer.
The larger of two consecutive integers is represented by x plus 4 Which expression represents the smaller integer?
x+3 and x+4 would be consecutive integers.
Is plus 1 an integer?
Yes, plus 1 is consider as positive one (+1). All positive and negative numbers are considered as integer.
If n plus 4 represents an odd integer the next larger number odd integer is represented by?
Every integer is either even (divisible by 2) or odd (not divisible by 2). Since an even number plus 1 is odd and an odd number plus one is even, because 1 does not divide 2. We know (n + 4) is odd. The next integer is (n + 4 + 1) = (n + 5), because an odd number plus 1 is even, (n + 5) is even. The integer after (n + 5) is (n + 6), since (n + 5) we know is even, (n + 6) must be odd. Since (n + 6) is the smallest integer that is greater than (n + 4) and is odd, so (n + 6) is the next odd integer.
When factoring is 9X squared plus 6X plus 4 prime?
This is (3x +2)2 so if x is an integer/3, this expression is the square of an integer so cannot be prime. Anything else, and it's not even an integer.
