Exercise 4 Page 77

Terms are separated by + or - signs. Coefficients are numbers that are multiplied by variables. Constants are numbers with no variable factors.

Terms: 3b and 12
Coefficients: 3
Constants: 12

Practice makes perfect

An algebraic expression is a combination of numbers, variables, and mathematical operations. Terms are separated by + or - signs. With this information in mind, let's identify the terms in the given expression. 3b + 12

We can see that the expression has two terms, 3b and 12. Next, we will identify the coefficients and constants. A coefficient is a number that is multiplied by a variable or variables. A constant is a number with no variable factors. 3b+ 12 The expression has one coefficient, which is 3, and a constant, which is 12. Let's organize this information in a table.

Terms	Coefficients	Constants
3b and 12	3	12
