Question

the number line shows an unknown number, d.
is d + 1 positive or negative?
positive
negative

Explanation:

Step1: Analyze range of d

From the number - line, we know that \(0\lt d\lt1\).

Step2: Add 1 to the inequality

If \(0\lt d\lt1\), then \(0 + 1\lt d + 1\lt1 + 1\), which simplifies to \(1\lt d + 1\lt2\).

Answer:

positive
