Answer 1

Resposta:

$2)\\ \\ a)~~33x+22y-55z~~=~~11(3x+2y-5z)\\ \\ b)~~6nx-6ny~~=~~6n(x-y)\\ \\ c)~~4x-8c+mx-2mc~~=~~4x(1+m)-2c(4+m)\\ \\ d)~~49-a^{2} ~~=~~\sqrt{49} -\sqrt{a^{2} }~~=~~7-a\\ \\ e)~~9a^{2} +12a+4~~=~~(3a+2)^{2}$

$3)\\ \\ Area=A=(x+1).(2x+3)\\ \\ A=2x^{2} +3x+2x+3\\ \\ A=2x^{2} +5x+3$
