Answer

Two solutions Explanation 1. Analyze the Absolute Value Equation The equation 72 = |p - 9| implies two possible cases for p: p - 9 = 72 and p - 9 = -72. 2. Solve for p in Both Cases Case 1: p - 9 = 72 \Rightarrow p = 72 + 9 = 81. Case 2: p - 9 = -72 \Rightarrow p = -72 + 9 = -63. 3. Count the Solutions There are two distinct solutions: p = 81 and p = -63.

Explanation

1. Analyze the Absolute Value Equation<br /> The equation $72 = |p - 9|$ implies two possible cases for $p$: $p - 9 = 72$ and $p - 9 = -72$.<br /><br />2. Solve for $p$ in Both Cases<br /> Case 1: $p - 9 = 72 \Rightarrow p = 72 + 9 = 81$.<br /> Case 2: $p - 9 = -72 \Rightarrow p = -72 + 9 = -63$.<br /><br />3. Count the Solutions<br /> There are two distinct solutions: $p = 81$ and $p = -63$.
