Final answer:
In the expression w+15x-9y+2z, each part separated by a plus or minus sign is considered a term. The terms in this expression are a. w, b. 15x, c. -9y, and d. 2z.
Step-by-step explanation:
To identify the term in the expression w+15x-9y+2z, we look at each part of the expression that is separated by a plus or minus sign. An expression is made up of terms that are added or subtracted from each other. In this context, the terms are different elements that may include numbers, variables, or products of numbers and variables.
- w is a term that represents a variable.
- 15x is a term that includes a coefficient (15) multiplied by a variable (x).
- -9y is a term that includes a negative coefficient (-9) multiplied by a variable (y).
- 2z is a term that includes a positive coefficient (2) multiplied by a variable (z).
Each of these parts, a. w, b. 15x, c. -9y, and d. 2z are terms within the given expression.
