Question

qual e o valor, e min explique ​

Answer 1

$w=-\frac{1}{4}.[\frac{2}{3}-(-1+\frac{1}{2})]$

$w=-\frac{1}{4}.[\frac{2}{3}-(-\frac{2}{2} +\frac{1}{2})]$

$w=-\frac{1}{4}.[\frac{2}{3}-(-\frac{1}{2})]$

$w=-\frac{1}{4}.[\frac{2}{3}+\frac{1}{2}]$

$w=-\frac{1}{4}.[\frac{4}{6}+\frac{3}{6}]$

$w=-\frac{1}{4}.\frac{7}{6}$

$w=-\frac{7}{24}$
