Answer:
231
Explanation:
I put the equation as 15^2+2(3) I'm guessing the x was suppose to be after the 2 because it doesn't make sense putting x in front of the two....
So the tiny 2 above the 15 means 15 is squared
15 squared = 225
225 + x(2)
If x = 3, then simply plug that into the equation
225 + 3(2)
225 + 6
231 is your answer
