Answer:
D. Negative 2a minus b
Explanation:
The additive inverse of the expression 2a + b is the expression that, when added to 2a + b, results in a sum of zero. The additive inverse is found by negating each term in the expression.
Therefore, the additive inverse of 2a + b is:
D. Negative 2a minus b
This is because when you add 2a + b to negative 2a minus b, the terms with "a" and "b" cancel out, resulting in a sum of zero.
