Six times the difference of a number and four

0 step by step is below so yeah

Step-by-step explanation:

4-4 = 0 * 6 = 0

First, since we must follow PEMDAS, we need to do the operation that is first, which is addition. 

-3.9 + 6.01  ← Adding a negative means subtracting, then giving the sign of the bigger number.

So now we solved those and we got this 2.11

Now, we need to subtract and re-write the expression.

2.11 - (-7.423) = 2.11 + 7.423= 9.533

Okso now we have our final answer, and we have the choices above.

The only answer that matches ours is the last one.

Final 9.533

Hope I helped ^_^
