Answer 1

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