Identify the numerical coefficient of the expression. –7t2
To identify the numerical coefficient of the expression –7t2, we need to understand the parts of the expression.
The expression –7t2 consists of two parts: a coefficient (-7) and a variable (t) raised to a power (2).
The coefficient is the numerical value that multiplies the variable. In this case, the coefficient is -7.
Therefore, the numerical coefficient of the expression –7t2 is -7.
