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 5 expressions are equivalent to 8x plus 16?
Well, darling, you've got yourself a simple algebraic equation. Five expressions equivalent to 8x + 16 could be 2(4x + 8), 4(2x + 4), 8(x + 2), 16(x/2 + 1), and even 8x + 8 + 8. Math can be a real hoot when you know your way around it!
What are two expressions that are equivalent to 8 plus 2x?
(16 + 4x)/2 2(4 + x)
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 are expressions that have the same value no matter what x represents called?

What is the difference between equivalent expressions and equivalent equations?
An expression does not equate to anything. An equation is equal to something. Expression: x+2 Equation: x+4=2x Equivalent expressions: x+2 and 2x-2 if x=4 Equivalent equations: x+4=2x and -x+10=2x if x=4
What 3 expressions are equivalent to 8x+24y+16?
8x + 16 = 2(4x + 8) = 4(2x + 4) = 8(x + 2) = 16((1/2)x + 1) = -8(-x - 2)
What does equivalent expressions in math mean?
It means that two expressions represent the same number; for example, 5 is equivalent to 3 + 2. If there are variables in the expression, it means that the two expressions will evaluate to the same number, for any value assigned to the variable or variables. For example, for any value of x, 2x is the same as x + x; therefore, the two are equivalent.
