An expression can be that, but it can also be a combination of such terms and other mathematical operations. For example,
3a + 27b^2/sin(27c) provided c is not 0.
The number is called the coefficient of the variable
It is the coefficient of the variable
factor
The number that multiplies a variable in an algebraic expression is called a coefficient. It is the numerical factor that is multiplied by the variable to form a term in the expression.
It is called the coefficient of the variable
That is often called the coefficient.
It is the coefficient of the unknown variable
the coefficient
A number or expression that can be multiplied to get another number or expression is called a factor.
A term in an expression?
The coefficient would be the number multiplied by the variable, in this case: 7
This question cannot be answered. You will have to give me more detail.
