Answer: The term in this expression is D. -3x
A term in an expression is a single mathematical entity, such as a variable or a constant. In the expression -3x - 7(x + 4), -3x is a term on its own, it is the product of -3 and x, and it doesn't have any other mathematical operation.
-7 is a constant, but it is not a term on its own because it has an operation with another term (x + 4)
(x + 4) is a term as well, it is the sum of x and 4.
So the term in this expression is -3x
