Answer 1

$\frac{ {(x - 2)}^{2} }{4y + 9} \times \frac{2y + 6}{ {x}^{2} - 4} = \frac{(x - 2)(x - 2)(y + 3)2}{(4y + 9)(x - 2)(x + 2)} = \frac{(x - 2)(y + 3)2}{(4y + 9)(x + 2)} \\ \\ \frac{(x - 2)(y + 3)2}{(4y + 9)(x + 2)} = \frac{(0.5 - 2)( - 1.5 + 3)2}{(4 \times ( - 1.5) + 9)(0.5 + 2)} = \frac{ - 1.5 \times 1.5 \times 2}{( - 6 + 9) \times 2.5} = \frac{ - 4.5}{7.5} = - \frac{45 \times10 }{10 \times75 } = - \frac{3}{5} = - 0.6$
