Answer:
9 in, or B
Step-by-step explanation:
We can easily apply the Pythagorean Theorem to this. You could either realize that this is a 3-4-5 Pythagorean triple or do the math by hand.
We start off by setting up the equation 12² + x² = 15². Simplifying, we get 144 + x² = 225, and then x² = 81 after subtracting 144 from both sides. Thus, the square root of x is 9, and so the answer is 9 inches.
Step-by-step explanation:
Given that the mean of the numbers is 12
so here
let's that one as x and another one as 2x since it is given that one is twice the other
Therefore we get
Given mean = 12
Hence it's 11 and 22
