Answer:

As we are told that the value of x is equal to 3, we are able to substitute this into our equation, so it becomes 2(3)^2. We then use the rules of BIDMAS, so we must square the number 3 first (meaning we multiply the number by itself), and then multiply it by two. 3^2 is 9, and 9 times 2 = 18. Therefore, the answer is 18.
