Final answer:
The expression that has an answer that is negative is (-48)+(-6).
Step-by-step explanation:
To determine which expression has an answer that is negative, we need to evaluate each expression.
A) (-48)+6 = -42, which is negative.
B) (-48)+(-6) = -54, which is negative.
C) (-6)(-3) = 18, which is positive.
D) 6x3 = 18, which is positive.
Therefore, the expression that has an answer that is negative is B) (-48)+(-6).
