Question

simplifique as expressões, reduzindo os termos semelhante​

Answer 1

$a)\:4m + m = m(4 + 1) = 5m\\\\b)\:-7x - x = x(-7 - 1) = -8x\\\\c)\:xy - 10xy = xy(1 - 10) = -9xy\\\\d)\:0,5m^{3} - m^{2} = m^{2}(0,5m - 1) = 0,5m^{3} - m^{2}\\\\e)\:6t - 4t - 2t = t(6 - 4 - 2 ) = t.0 = 0\\\\f)\:15a + 10 - 3a = a(15 - 3) + 10 = 12a + 10$
