The expression given is 5 - mn - n. In this expression, the second term is -mn. The coefficient of the second term is -1, as it is understood that when a variable is written without a coefficient, it is considered to have a coefficient of 1.

When the following expression is written in simplest form what is the coefficient of the variable term -1.5r plus 6r and ndash 12.2r?

To find the coefficient of the variable term, we need to combine like terms. The coefficient of the variable term -1.5r is -1.5. The coefficient of the variable term 6r is 6. The coefficient of the variable term -12.2r is -12.2. Thus, when combined, the coefficient of the variable term is -1.5 + 6 - 12.2, which simplifies to -7.7.

What are terms coefficients and constants?

The numerical multiplier of any term in an algebraic expression is a coefficient. The constant term is a coefficient which does not have a variable associated with it.


What is a coefficient?

A coefficient is a number in front of a variable (i.e. multiplied by it).For example, in the expression x2 - 10x + 25, the coefficient of x2 is 1 and the coefficient of x is -10. The third term, 25, is a constant.If the expression were -x2 + 10x + 25, the coefficient of x2 would be -1, and the coefficient of x would be 10.

What is the number that multiplies a variable?

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.


What are the example of the numerical coefficient?

In mathematics, a numerical coefficient is a constant factor in a term of an algebraic expression. For example, in the term 5x, the numerical coefficient is 5. In the expression 2y^2, the numerical coefficient is 2. Numerical coefficients can be positive, negative, integers, fractions, or even irrational numbers.


What is the coefficient in the expression shown 42 + 2c?

42 and 2c such that they are separated by a addition sign. Now, the term 2c is a variable term such that it is obtained when 2 is multiplied with the variable c. Hence, 2 is the coefficient of the expression.
