Because "x" is a variable, it is the same as 9 times x.
X+9
9*(x+ 2)
They are two terms of an algebraic expression.
It is an algebraic expression
3 plus x = 9
As an algebraic expression it is: 9-x
X+9
Assuming the number is x, then: x + 9
9*(x+ 2)
They are two terms of an algebraic expression.
It is an algebraic expression
x/2 - 9
3 plus x = 9
If the algebraic expression can be written in the form of a(x)/b(x) where a(x) and b(x) are polynomial functions of x and b(x) ≠0, then the expression is a rational algebraic expression.
The algebraic expression for eleven subtracted from X is: X - 11
