Explanation:
An expression is a combination of numbers, variables, and operators that represents a value. It can also include parentheses, exponents, and functions.
Let's look at each option to determine which one is an expression:
a) 10 - This is a number, not an expression.
b) 3 - This is also a number, not an expression.
c) 1/2 - This is a fraction, not an expression.
d) 4x + 7 - This is an expression because it contains a variable (x), numbers (4 and 7), and an operator (+) that represents a value.
Therefore, the correct answer is option 'D'.
