c) (5)(4)+(4)(6) d) (-6)(1)-(-5)(-6) doy 44 ptos porfa

Answer 1

a)
$3 \times 4 + 3 \times ( - 2) = 3(4 - 2) = 3(2) = 6$

b)
$- 4 \times ( - 2) - ( - 2) \times 6 \\ 8 - ( - 12) = 8 + 12 = 4(2 + 3)$

c)
$5 \times 4 + 4 \times 6 = 4(5 + 6) = 4(11) = 44$

d)
$- 6 \times 1 - ( - 5)( - 6) = - 6(1 + 5) = - 6(6) = - 36$
