Final answer:
The expression 6 minus (negative 8) is equivalent to 14.
Step-by-step explanation:
The expression 6 minus (negative 8) can be simplified by changing the subtraction of a negative into addition. The negative sign in front of the 8 can be interpreted as multiplying by -1, so the expression becomes 6 + (-1)(-8). Since multiplying two negatives gives a positive, (-1)(-8) is equal to 8. Therefore, the expression 6 minus (negative 8) is equivalent to 6 + 8, which equals 14. Thus, none of the provided options are equivalent to 6 minus (negative 8).
