Question

What is (n+8)+(n-12)enter the answer when your done

Answer 1

To simplify the expression (n+8)+(n-12), we combine like terms to get 2n and add the constant terms to get -4. The simplified expression is thus 2n - 4.

Step-by-step explanation:

The student's question is asking for the simplification of the expression (n+8)+(n-12).

To simplify the expression, we combine like terms, which are the terms that contain the same variable to the same power. Here, our like terms are n terms. We combine these terms by adding their coefficients.

So, the simplification process is as follows:

• Combine n terms: n + n = 2n
• Combine constant terms: 8 - 12 = -4
• Add the results: 2n + (-4) = 2n - 4.

Therefore, the simplified form of (n+8)+(n-12) is 2n - 4.
