Answer:
The answer is
<h2>12</h2>
Step-by-step explanation:
The above variation is written as

where k is the constant of variation
when y = 16
x = 3
k = yx²
k = 16(3)²
k = 16 × 9
k = 144
The formula for the variation is

when y = 1
We have

Cross multiply
x² = 144
Find the square root of both sides
x = √144
x = 12
