Simplifying the expression 3 - (4x - 5) + 6 by first distributing the negative sign inside the parentheses gives: 3 - 4x + 5 + 6. Then, combining like terms gives: -4x + 14.
Therefore, the simplified expression is: D) -4x + 14.

To simplify the expression 3 - (4x - 5) + 6, we need to follow the order of operations, which is Parentheses, Exponents, Multiplication/Division (from left to right), and Addition/Subtraction (from left to right).
First, we can simplify the expression inside the parentheses by distributing the negative sign:
3 - (4x - 5) + 6 = 3 - 4x + 5 + 6.
Next, we combine like terms:
= (3 + 5 + 6) - 4x.
= 14 - 4x.
Therefore, the simplified expression is 14 - 4x.
So the correct answer is D) -4x + 14.

To simplify the given expression, 3 - (4x - 5) + 6, we can start by applying the distributive property to the parentheses.
Inside the parentheses, - (4x - 5), we need to distribute the negative sign to each term inside. This would give us -4x + 5.
Now, the expression becomes 3 - 4x + 5 + 6.
Next, we can combine like terms. The constants 3, 5, and 6 can be added together to give us 14.
So, the expression simplifies to -4x + 14.
Therefore, the correct answer is option D) -4x + 14.
