A
since the 3 is outside the radical then 
= 3, hence
x = 9

30x10=300 Stamps (remember to add the "stamps" or your teacher may count it against you)
33 pupils - 17 girls = 16 total boys in the class

Answer: 2
Question #1
the answer is A
question #2
the answer is A
The answer is -3. Adding a negative onto a positive is just like subtracting from the positive. So, first off, 5+(-3) is 2. Then, subtracting 6 from the 2 will give you a negative number, -4. Subtracting a negative changes the sign to be a plus, so you plus one onto the -4. This leaves you with the answer of -3.
