Question

simplify by combining like terms.
12c + 5c + 4 + 2c
?c +
enter the number that goes in the green box.

Explanation:

Step1: Identify like terms with \( c \)

The terms with \( c \) are \( 12c \), \( 5c \), and \( 2c \).

Step2: Combine the like terms

Add the coefficients of these terms: \( 12 + 5 + 2 = 19 \). So the combined term for \( c \) is \( 19c \), and the constant term remains \( 4 \). The number in the green box (coefficient of \( c \)) is \( 19 \).

Answer:

19
