I believe the correct answer is C) 36+12
The equation is 4(9+3). Because of the fact that the four is on the outside, you can distribute the it so both the 9 and the 3.
9 x 4=36
4 x 3= 12
After doing this you set up your new equation which is 36 + 12!
That’s how I got this answer, hope it helps lol.
