Answer 1

Resposta:

$a)\\ \\ 5x+1+3x+6=\\ \\ 5x+3x+1+6=\\ \\ 8x+7\\ \\ b)\\ \\ 3x^{2} +4x+5x^{2} +2x=\\ \\ 3x^{2} +5x^{2} +4x+2x=\\ \\ 8x^{2} +6x\\ \\ c)\\ \\ 2x^{3} y+3+3x^{3} y+5=\\ \\ 5x^{3}y +3x^{3} y+3+5=\\ \\ 8x^{3} y+8\\ \\ d)\\ \\ 4x^{2} y+3x+5x^{2} y+4x=\\ \\ 4x^{2} y+5x^{2} y+3x+4x=\\ \\ 9x^{2} y+7x$
