Let's simplify both expressions.

Expression 1: $-3(7x + 11)$

Distribute $-3$ to both terms inside the parentheses: $-3 \times 7x = -21x$ $-3 \times 11 = -33$ So, the simplified expression is: $-21x - 33$

Expression 2: $2(2x - 4)$

Distribute $2$ to both terms inside the parentheses: $2 \times 2x = 4x$ $2 \times -4 = -8$ So, the simplified expression is: $4x - 8$

Final Simplified Expressions:

1. $-21x - 33$
2. $4x - 8$
