Final answer:
The expression -x^3 + 3x^3 - 4x + 5 simplifies to 2x^3 - 4x + 5, with coefficients 2 and -4, a constant of 5, and three terms.
Step-by-step explanation:
The question is asking to identify the coefficients, the constant, and the number of terms in the polynomial expression -x^3 + 3x^3 - 4x + 5.
First, let's combine like terms:
-x^3 + 3x^3 = 2x^3
So, the simplified expression is 2x^3 - 4x + 5.
The coefficients of this expression are the numbers multiplying the variable terms: 2 (for 2x^3) and -4 (for -4x). The constant is the term without a variable, which is 5. The number of terms in the simplified expression is three: 2x^3, -4x, and 5.
