d. \( -\square-\frac{5}{2}=-\frac{17}{4} \)

To solve for the missing square, first, let's rewrite the equation in a simpler form. We have: \[ -\square - \frac{5}{2} = -\frac{17}{4} \] To isolate the square, we can add \(\frac{5}{2}\) to both sides: \[ -\square = -\frac{17}{4} + \frac{5}{2} \] Next, convert \(\frac{5}{2}\) to a fraction with a denominator of 4: \[ \frac{5}{2} = \frac{10}{4} \] Now substitute back into the equation: \[ -\square = -\frac{17}{4} + \frac{10}{4} \] This gives us: \[ -\square = -\frac{7}{4} \] Multiplying both sides by -1, we find: \[ \square = \frac{7}{4} \] So, the answer is: \[ \square = \frac{7}{4} \]
