a. $\quad 3$ b. $\quad 4$ c. $\quad 1$ d. $\quad$ No like terms.

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 $ 4y+1+3x$, three 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 $4y$ is $4.$ c. A term that consists of just a number is called a constant term. In $4y+1+3x$, the constant term is $1$. 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. In $4y+1+3x,$ no two terms have identical variable factors.
