Answer:
We need to find which expressions are equivalent to
,
or neither.
: We extract the greatest common factor which is 6. Remember, when we extract a GCM, we divide each term by it.

Therefore, this expression is equivalent to neither of the given expressions.
: We just need to apply the distributive property.

Therefore, this expression is equivalen to
.
We use the same process to the other expressions.



, equivalent to neither.
Answer: A number with the same absolute value of 23 is -23.
Explanation: The absolute value of a number is how far it is from zero, and the absolute value of a number is always positive, unless the number is 0, in which case the absolute value is neutral, and the absolute value is 0.
Examples: 6 is 6 away from zero, so the absolute value of 6 is 6.
−6 is 6 away from zero, so the absolute value of −6 is 6.
Answer:
30:16-15:8 That is simplified and I divided it by two.
