What is a number sentence that shows how two or more expressions are not equal?
If the expressions are w, x, y, z then to show that no two of them are equal is shown by(w-x)*(w-y)*(w-z)*(x-y)*(x-z)*(y-z) ≠0.Note that w .ne. x AND x .ne. y AND y .ne. z is not enough since it is possible for x = z.
How are equivalent expressions used?
You can use them to find a variable. Lets say you have two equivalent expressions with the same variable... x + 2x - 42 = 0 2x - 28 = 0 If you combine these equivalent expressions you ahve... x + 2x - 42 = 2x - 28 In all of the expressions you have x = 7 There are also other applications but its confusing to explain.
What is x 2m-nxx plus 4?
It is two expressions which are disjoint.
Is x-x a variable expression?
Yes. It is equal to zero. Yes, mathematical expressions can contain numbers, variables, and mathematical operations but do not contain an equal sign or inequality sign.
What are the 5 example of an equations?
For example:1 = 1 1 = 0 x = 5 x = x + 1 y = x + 5 So basically, any two expressions (numbers, or something that can be calculated to give a number), with an equal sign in between.
What are equivalent expressions?
Two or more expressions (equations are examples) that are equal to or equivalent to each other; for example: (X+2)(X+4) = X^2+6X+8.
What values of x make the two expressions below equal apex?
All real numbers

In algebraic expressions is there a solution?
In many cases you can simplify an algebraic expression. You don't really "solve" them; an equation can be solved. An equation is a declaration that two expressions are equal, for example, x + 3 = 10.
Is tan squared x equal tan x squared?
Yes. Both expressions are the same.

X-1 and x3?
These are two algebraic expressions.
If f(x)-5x-4 and g(x) -3(x)-2 find (f plus g)(x)?
Just add the expressions for the two functions - the part on the right of the equal sign.
What are expressions that have the same value no matter what x represents called?
algebraic expressions
Does an expression have an equal sign?
No, expressions do not have equal signs. Equations do, though. You can think of it like this: Equtions have EQUAl signs, while expressions do not.No, an expression cannot have an equal sign. If it were to have an equal sign, it would then be an equation.
What is alegbriac inequality?
It means that two expressions are not equal, as in a # b (Using "#" for inequality). A statement that includes "less than", "less than or equal", "greater than", or "greater than or equal", can also be considered an inequality, for example, | x | < 5
Can the same variable equal two different numbers in one equation?
No, but a variable can have more than one value in an inequality such as x > 10. In that inequality, x can be 11, 12, 13, 14, or anything else higher than 10.That is not to say, however, that the same variable can't be equal to two different expressions or formulas. The equations x=10 and x=y+5 are completely valid. In fact, those expressions imply that 10=y+5, or that y=5.
