It is: 3
n is the variable.
3 is called the constant term and the 6n is called the linear term.
In the expression 6n+3 the variable or the unknown is n
4
It can be simplified to: 4m-2n
11m + 6n - 2m + 9n = 9m + 15n or 3(3m + 5n)
It is: 3
6 is the coefficient of n in this expression.
n is the variable.
m+ (6n)
3 is called the constant term and the 6n is called the linear term.
In the expression 6n+3 the variable or the unknown is n
n4+6n3+11n2+6n+1 cannot be simplified any further based on addition, you can however, multiply each term together, not adding it.
M+6n
3 is called a constant term.
The unknown variable in the expression: 6n+3 is n
