Gente doy coronita ayúdenme en esto por faaaaaaaaa

Answer 1

Respuesta:

$\\ P =6x {}^{2} - 14x + 6 \\ A = 12x {}^{3} - 38x {}^{2} - 18x + 2$

Explicación paso a paso:

$A = B \times h \\ P = 2B + 2h \\ \\ B = 3x {}^{2} - 11x + 1 \\ h = 4x + 2 \\ \\A =(3x {}^{2} - 11x + 1)(4x + 2) \\ A =12x {}^{3} + 6x {}^{2} - 44x {}^{2} - 22x + 4x + 2 \\ A =12x {}^{3} - 38x {}^{2} - 18x + 2 \\ \\ P =2(3x {}^{2} - 11x + 1) + 2(4x + 2) \\ P =6x {}^{2} - 22x + 2 + 8x + 4 \\ P =6x {}^{2} - 14x + 6$
