Final answer:
Option B) -212-3 has a negative value.
Step-by-step explanation:
The correct answer is option B) -212-3.
To determine which expression has a negative value, we need to evaluate each option.
A) 7+3(-4)(2) = 7+3*-8 = 7-24 = -17
B) -212-3 = -215
C) (15-7)-(9-3) = 8-6 = 2
D) -5[7+(-14)]-30 = -5*(-7)-30 = 35-30 = 5
Based on the evaluations, it is clear that option B) has a negative value.
