Does the expression d-12 have a grater value when d=42 or when d=46

To determine whether the expression d-12 has a greater value when d=42 or when d=46, we simply substitute the values of d into the expression and compare the results.

When d=42:
d-12 = 42-12 = 30

When d=46:
d-12 = 46-12 = 34

Comparing the two results, we find that the expression d-12 has a greater value when d=46, since 34 is greater than 30.
