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.
Which expressions are equivalent to the one below Check all that apply. 8x?
Expressions equivalent to (8x) include any expression that can be simplified or factored to result in (8x). Examples include (2(4x)), (16(x/2)), and (4(2x)). Any expression that maintains the same value as (8x) when simplified is also considered equivalent, such as ((8/1)x).

What are 2 equivalent expressions for 5b plus 5b?
5b + 5b = 2 x 5b
What expressions represent the product of three less than x and five more than twice x?
The expression for "three less than x" is ( x - 3 ), and the expression for "five more than twice x" is ( 2x + 5 ). The product of these two expressions can be represented as ( (x - 3)(2x + 5) ). Thus, the expression representing the product is ( (x - 3)(2x + 5) ).
What 5 expressions are equivalent to 8x plus 16?
Oh, what a happy little question! 8x plus 16 is like a beautiful tree with many branches. Some expressions that are equivalent to 8x plus 16 include 2(4x + 8), 4(2x + 4), 16 + 8x, and 8(x + 2). Just like painting a lovely landscape, there are many ways to represent the same mathematical idea.
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?
algebraic expressions

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.
Writing algebraic expressions five less than a number?
