In the Expression(6 - 9t+8), 9t represents coefficient and variable.
Step-by-step explanation:
An algebraic expression usually consists of constants, variables and, at least one arithmetic operators like addition, subtraction and coefficients.Variable can be any alphabetic letter from A to Z and it represents a certain unknown mathematical value.Coefficient can be any number being multiplied by a variable.
In the given expression, 6-9t+8 , 9 is the coefficient being multiplied by variable ‘t ‘ . So 9t represents coefficient and variable.
