Question

what is the coefficient of the second term in this expression? a + 4c + 7b

Explanation:

Step1: Identify the second term

In the expression \(a + 4c + 7b\), the terms are separated by addition signs. So the first term is \(a\), the second term is \(4c\), and the third term is \(7b\).

Step2: Determine the coefficient

The coefficient of a term is the numerical factor multiplied by the variable(s). For the term \(4c\), the numerical factor (coefficient) is \(4\).

Answer:

4
