Is the square root of a variable an irrational number?
That will depend on the value of the unknown variable
What is the root definition for invariably?
Variable, or if you're a purist - vary.
What is a value of the variable that makes an algebraic sentence true?
It is the solution or root of the equation.
What is a nonpermissable replacement in rational expressions?
Replacing the variable in the denominator by a root of the denominator.
What is the difference between a polynomial and radical expression?
A polynomial is an expression of various exponentials of a variable wich may or may nor have coefficients and constants. The coefficients may have a radical, square root, cube root etc, but not the variable. A radical expression is any expression involving square roots, cube roots, etc. These may have the variable inside the radical but do not have to have them. sq root (5) is a radical expression, so is sq root (x) 3x2 + 2x - 9 is a polynomial, so is x + sq root (5)

Words that contain root word vari?
variable
When one factor affects another?
Dependent Variable - Note the root word DEPEND. So a dependent variable is when on variable depends on/affects the other.
A letter that takes a place of a number?
a variable

Variable, or if you're a purist - vary.
How do you find the square root of a variable squared plus sixteen?
factor it
What best describes a root of a polynomial?
A value of the variable when the polynomial has a value of 0. Equivalently, the value of the variable when the graph of the polynomial intersects the variable axis (usually the x-axis).
What is a value of the variable that makes an algebraic sentence true?
It is the solution or root of the equation.

What is a root of a polynomial function?
A value of the variable that makes the polynomial equal to zero (apex)
What is A value for a variable that makes a statement true?
Such a value is called a "solution" or "root" of an equation.
