On a math test a student, Sarah, has to identify all the coefficients and constants of the expression 6n + 5 +m. Sarah says that is a coefficient and 5 is a constant. Identify all the coefficients and constants of the expression. What error might Sarah have made?

coefficientis anumberbefore avariable. (for example, 12d)variableis aletter(for example, a)constantis anumberwith novariables(not 6s, but 6)Answer: Hence the coefficients are 5 and 1 and constant is 9 and Sarah made a mistake by not writing the coefficient of m
