Answer:
3rd expression has a positive value.
Step-by-step explanation:
(1) -4 + (-5) [tex][\frac{(-6)}{(-3)}][/tex]
= -4 + (-5) × 2
= -4 -10
= -10
(2) 8 [tex][\frac{10}{2(-2)}][/tex]
=[tex]\frac{80}{(-4)}[/tex] = -20
(3) 3 [tex][\frac{-64}{8}]+25[/tex]
= 3(-8) + 25
= -24 + 25
= 1 [positive value]
(4) [tex]\frac{(-2)(-5)(-3)}{10}[/tex]
[tex]=\frac{+10(-3)}{10}[/tex]
= -3
3rd expression has a positive value.
