To evaluate the expression \( 18 + 4(28) \) using the properties of operations, we can follow these steps:
1. **Evaluate the product**: According to the order of operations (PEMDAS/BODMAS), we first calculate the multiplication.
\[
4(28) = 112
\]
2. **Add the result to 18**: Now we can substitute \( 4(28) \) with 112 and then add it to 18.
\[
18 + 112 = 130
\]
Thus, the value of the expression \( 18 + 4(28) \) is \( 130 \).
To summarize, we used the property of operations that states we should perform multiplication before addition, which allowed us to simplify the expression step by step.
