Solution Steps

Step 1: Evaluate the First Expression

We start with the expression \( 9 + 7(4 + 8) \). First, we evaluate the parentheses: \[ 4 + 8 = 12 \] Now, substitute back into the expression: \[ 9 + 7 \cdot 12 \] Next, perform the multiplication: \[ 7 \cdot 12 = 84 \] Finally, add: \[ 9 + 84 = 93 \]

Step 2: Evaluate the Second Expression

Next, we evaluate the expression \( (9 + 7)(4 + 8) \). First, we calculate each set of parentheses: \[ 9 + 7 = 16 \] \[ 4 + 8 = 12 \] Now, substitute back into the expression: \[ 16 \cdot 12 \] Perform the multiplication: \[ 16 \cdot 12 = 192 \]

Final Answer

For the first expression: \( \boxed{93} \)
For the second expression: \( \boxed{192} \)
