Final answer:
The expression '1.3x - 2.7x^2 - 5.4x + 3' has four terms, which are 1.3x, -2.7x^2, -5.4x, and the constant 3.
Step-by-step explanation:
The correct answer is option d. The given expression 1.3x - 2.7x2 - 5.4x + 3 consists of four separate terms. Each term is a unique combination of variables (x) and constants that are either added or subtracted from one another.
The first term is 1.3x, the second term is -2.7x2 (note that this is a squared term, which makes it distinct from the linear terms), the third term is -5.4x, and the fourth term is the constant 3. When identifying terms, coefficients, variables, and their exponents are taken into account.
In the given expression, there are three terms: 1.3x, -2.7x^2, and -5.4x. Each term is separated by a plus or minus sign. A term is defined as a combination of a coefficient and a variable or variables raised to a power. In this case, the terms have different coefficients and powers of x.
