The solution is 3x^2
For solve the equation need to use the limit. I don’t know if you already study it
20/45 = x/18
(cross multiply and sole)
360=45x
x=8

Since both have a ratio of 8 feet to one second, we draw the conclusion that the situation may be described using a proportionate relationship.
<h3>Is the relationship shown proportionally?</h3>
Keep in mind that the formula for a proportionate connection between two variables is:
y = k*x
where k is the proportionality constant.
If we get the same proportionality constant for the two supplied pairs of variables, then the presented scenario is proportional. Let's define x as the time and y as the distance.
After the first pair has traveled 24 feet in 3 seconds:
24 feet = k*3s
K = 8 ft/s for (24 ft/3s)
After the second pair moves 40 feet in 5 seconds:
40ft = k*5s
K = 40ft/5s 8ft/s
Then, because both have a ratio of 8 feet to one second, we draw the conclusion that the situation may be described using a proportionate relationship.
