Answer 1

Answer:

465

Step-by-step explanation:

$\frac{ \frac{( - 9 - 11)}{ - 4} }{ - {7}^{2} + (11 \times {2}^{2})} \\ = \frac{ \frac{ - 20}{ - 4} }{49 + (11 \times 4)} \\ = \frac{ - 20}{ - 4} \times \frac{49 + 44}{1} \\ = \frac{ - 20}{ - 4} \times \frac{93}{1} \\ = \frac{ - 1860}{ - 4} \\ = 465$
