n is the variable.
It is an expression in the variable, a.
Yes. Anything which you can evaluate (calculate) to get a number is a numerical expression. Thus, all of the following are numerical expressions:5x (if the variable stands for a number)1 + 25 / 3square root of (5 / 3)In general:* Any number* Any variable that stands for a number* An addition, subtraction, multiplication, division, or power that involves numerical expressions is again a numerical expression (as long as the operation makes sense - for example, you can't divide by zero)* Many mathematical functions, with a numerical expression as a parameter - for example, sin(5 + 3), ln(10), etc.
To evaluate a variable expression, replace all the variables with numbers and simplify the resulting numerical expression. 3m for m = 9 3(9)=27
It would be possible to answer the question if it was written in English. What do you really want to know?
In the expression 6n+3 the variable or the unknown is n
You cannot because the expression still contains the unknown variable y.
It is either 3*2 + a or 3*(2 + a)
The numerical expression for 36 divided by the sum of 9 and 3 is 36 / (9 + 3).
in mathematics, numerical coefficient refers to the constant multiplicative factors attached to the variables in an expression are known as Numerical Coefficient. It differs from Literal Coefficient.The Numerical Coefficient is always written in front of the variable as shown in the expression given below: , where are numerical coefficients.Numerical Coefficient is more frequently referred as Coefficient.the numerical coefficient for the term 10x4 is 10.The numerical coefficients for the expression 3x2 + x + 1 are 3, 1, and 1.
The unknown variable in the expression: 6n+3 is n
