#### Work Step by Step

a. The terms of an algebraic expressions are those parts separated by addition. It can be a number, a variable, or a number times one or more variables. In $3x+5$, TWO terms are separated by addition b. The numerical part of a term is called its coefficient. If a term is written without a coefficient, the coefficient is understood to be 1 The numerical coefficient of $3x$ is $3.$ c. A term that consists of just a number is called a constant term. In $3x+5$, the constant term is $5$. d. The parts of each term that are multiplied are called the factors of the term Like terms are terms that have exactly the same variable factors. $3x$ and $5$ do not have identical variable factors. There are no like terms,
