Question

The question is on equivalent expressions and properties of addition

Answer 1

Answer:

Both drop-down answers are 0

Step-by-step explanation:

You are just replacing the x with a 0.

ALSO: The question at the top: Yes 2x + 6x is equivalent to 9x in this equation, because multiplying anything times 0 equals 0, so it doesn't matter what number comes before the x, it will always equal 0.

So when x = 0: 2x + 6x = 0, and 9x = 0, they are equivelant.
