Answer 2

Explicación paso a paso:

$a = b \times h \\ \frac{ {a }^{2} + a - 6 }{ {a}^{3} + 2a} = x \times \frac{a - 2}{a} \\ \frac{(a + 3)(a - 2)}{( {a}^{3} + 2a)(a - 2)} = \frac{x }{a} \\ \frac{a + 3}{ {a}^{3} + 2a } = \frac{x}{a} \\ x = \frac{ {a}^{2} + 3a }{ {a}^{3} + 2a}$

$\frac{b + 1}{b +2} \times \frac{ {b}^{2} }{b - 2} = \frac{(b + 1)( {b}^{2}) }{(b + 2)(b - 2)} = \frac{ {b}^{3} + {b}^{2} }{ {b}^{2} - 4}$

perímetro

$\frac{4 {m}^{2} }{ {m}^{2} - 16} + \frac{4 {m}^{2} }{m - 4} + \frac{2}{m - 4} \\ \frac{8 {m}^{2} }{ {m}^{2} - 16 } + \frac{2}{m - 4} = \frac{8 {m}^{2} + 2m + 8 }{ {m}^{2} - 16}$

$2 \times \frac{5m + 1}{m + 4} + 2 \times \frac{ - 3}{m - 6} \\ \frac{10m + 2}{m + 4} - \frac{6}{m - 6} \\ \frac{10 {m }^{2} - 64m - 36 }{ {m}^{2} - 2m - 24 }$
