The product of two numbers is 450.the first number is half the second number. which can be used to find x, the greater number?

First, we must define the two numbers using x. We already know that the greater number is x. However, the smaller number is half the greater number. This can be represented by 1/2x. Now, we can create a multiplication equation to find the value of x. This equation would be x(1/2x) = 450. This can then be simplified to 1/2x^2 = 450, then x^2 = 900. Finally, x = 30, or -30. Since the question is only asking for an expression, the answer would be x(1/2x) = 450.

Hope this helps!
