Answer 1

Respuesta:

$2) \: \frac{25 {x}^{2} + 15x + 35x }{5x} = 5 {x}^{2} + 3x + 7 \\ 3) \: d(x) = (5x + 1)(4x + 2) \\ d(x) = 20 {x}^{2} + 14x + 2 \\ 4) \: \frac{12x {}^{m + 3} }{6x {}^{10} } \\ \frac{( {2}^{2} \times 3)x {}^{m + 3} }{(2 \times 3) {}^{10} } \\ \frac{{2x}^{2m + 6} \times 3x {}^{m + 3} }{ {2x}^{10} \times {3x}^{10} } = 2x {}^{2m - 4} \times 3 {x}^{m - 7} \\ m - 7 = 5 \\ m = 12$
