Question

Brianna's teacher asks her which of these three expressions are equivalent to each other. which is equivalent

Answer 1

Answer:

Please specify what the three expressions are.

Step-by-step explanation:

From what I understand, you need to set the expressions equal to each other. For instance, if one is 2(x-3) and the other is 2x-6, you could write it as:

$2(x-3)=2x-6$

Then, by evaluating it, you would get:

$2x-6=2x-6$ by distribution over subtraction.

$2x-6+6=2x-6+6$ by the additive property of equality

$2x=2x$ Simplify.

$x=x$ by the reflexive axiom.

Since x will always equal itself, 2(x-3) and 2x-6 are equivalent.

Therefore, if the expressions, once set equal to each other, result in the equation x=x, or any other expression in which one quantity equals itself, the two expressions are equal.

Sorry I could not be of more help, but you did not specify what the expressions were.
