Answer:
41.4 I believe
Explanation:
First we start in the () so we do 45+4= 49.
Next we divide 23 by 3 and we get 7.66666667, but we reduce that to 7.6.
Then we have 7.6 I don't know the sign we have to use, I used subtraction, so we do 7.6 - 49, which actually gives us -41.4,
Let me know if you have any questions. I couldn't do this 100% because I didn't know the choices but try this and if not, I apologize.
