The graph of this equation is shown in the figure below. We know that this equation is given as follows:
So, it is obvious that this is not a representation of a rain gauge. This graph represents a parable, but the rain gauge seems to be more like a <span>truncated cone</span>
3x + 24 = (3)(x) + (3)(8) You can see that there is multiplier 3 near x and 8. You can factor it and make 3x + 24 = 3(x + 8) So, the answer is 3. Hope this helps!
