Question

Calcule as expressões. A) (-x/2).(4y/3). 5. B) (-4a/3).(6ab/4) + Ab/2=

Answer 1

Boa tarde

a)

 (-x/2)*(4y/3)*5. = -(10/3)xy

b)

(-4a/3)*(6ab/4) + ab/2 

= ab * (-2a + 1/2) 

Answer 2

A)
$( -\frac{x}{2}) . (\frac{4y}{3}). 5 =$

$( -\frac{4xy}{6}) . 5 =$

$-\frac{20xy}{6} =$

$-\frac{10xy}{3} =$


B)
$(- \frac{4a}{3}) . ( \frac{6ab}{4}) + \frac{ab}{2} =$

$- \frac{24a}{12} + \frac{ab}{2} =$

$- \frac{4a}{2} + \frac{ab}{2} =$

$- \frac{4a + ab}{2}$
