SOMEONE GOOD AT MATH PLEASE HELP ME TODAY ASAP WILL GIVE BRAINLIEST

Provide the reason for Step 4 in the following proof.

Prove:

Chart with two columns and four rows. The first column is labeled Statements and the second column is labeled Reasons. First column row one: negative open parenthesis a plus b close parenthesis plus a equals negative a plus negative b plus a. Second column row one: Distributive property. First column row two - equals negative a plus negative b. Second column row two - Communicative Property of Addition. First column row three - equals zero plus negative b. Second column row three - Additive Inverse Property. First column row four - equals negative b. The second column row four is blank.


Additive Inverse Property


Commutative Property of Addition


Identity Property of Addition


Definition of Subtraction

Answer 1

Identity Property of Addition


You can see on the chart that it is asking for the reasoning as to why the value “-b” is the same as “-b + 0”. We know that this is because adding zero to a number does not change its value.

“The identity property of addition says that the sum of 0 and any number is that number.”

Answer 2

Answer:

Identity Property of Addition

Step-by-step explanation:

The identity property of addition says that the sum of 0 and any number is that number. This is true because the definition of 0 is "no quantity", so when we add 0 to -b, the quantity of -b doesn't change!
