Question

subtract.
(8r + 8) - (r + 4)

Explanation:

Step1: Remove parentheses

To subtract the two expressions, we first remove the parentheses. When we have a subtraction sign in front of a parentheses, we distribute the negative sign to each term inside the parentheses. So, \((8r + 8) - (r + 4)\) becomes \(8r + 8 - r - 4\).

Step2: Combine like terms

Next, we combine the like terms. The like terms with \(r\) are \(8r\) and \(-r\), and the constant like terms are \(8\) and \(-4\). Combining the \(r\) terms: \(8r - r = 7r\). Combining the constant terms: \(8 - 4 = 4\). So, putting it together, we get \(7r + 4\).

Answer:

\(7r + 4\)
