Let's break it down step by step! First, evaluate \( -4 \times (-5) \). When you multiply two negative numbers, the result is positive, so: \[ -4 \times (-5) = 20 \] Now, substitute that back into the expression: \[ 20 - 9 \] Next, subtract \( 9 \) from \( 20 \): \[ 20 - 9 = 11 \] So, the final answer is: \[ \boxed{11} \]
