The correct answer is b, x < -3.
Since the area shaded is left of x = -3, x has to be less than -3.
You do them in the order of operations, for example, on the 1st one you did 3x5 first and got 15, and then you added 2 and got a total of 17. On the second one, you did2x4 which is 8 and the you added 3 and made it a total of 11. So basically you do the last 2 boxes first, the add/subtract the first from the total of the other 2.
I'll give you a hint. A whole number is not negative. (I think 0 is not whole as well)
Prime numbers are numbers that can be multiplied more times than just one and itself. And odd numbers are numbers that you can only multiply by one and itself
