Final answer:
The terms in the expression are 7, 3D², and D/4, with 3 and 1/4 being the coefficients and 7 being the constant.
Step-by-step explanation:
In the expression 7 + 3D2 + D/4, the terms are 7, 3D2 (3 times D to the power of 2), and D/4.
The coefficients are the numerical factors of the variables, so in this case, they are 3 for the term 3D2 and 1/4 for the term D/4.
Note that while D and D2 are not coefficients, they are just variables and their respective powers. The term without a variable (7) is the constant.
Therefore, in the provided expression, there is only one constant, which is 7.
