Answer:
The square root of x will be evaluated first before the addition of 5. Hence (-3)^2 = 9 and 9 +5 = 14, as per your teacher's answer, which is correct. The answer would not be -4.
-1/2 and -2 would be the answer
This would be because when you plug these number instead of x the answer is equal to or less than 13
The product of 5 and 2/3 is 5.6666
