Answer:
The correct answer is C. 3 (-64 ÷ 8) + 25
Step-by-step explanation:
Let's solve the four expressions to find out the positive one, this way:
A. - 4 + (-5) (-6) ÷ (-3)
= -4 + 30 ÷ -3
= - 4 - 10 = - 14
B. 8 [10 ÷ (2) (-2)]
= 8 [10 ÷ -4]
= 8 * - 2.5 = -20
C. 3 ( -64 ÷ 8) + 25
= 3 ( -8) + 25
= - 24 + 25 = 1
D. -2 (-5) (-3) ÷ 10
= - 30 ÷ 10 = -3
As we can see, after solving the four expressions, the only with a positive result is C. 3 ( -64 ÷ 8) + 25
