Answer:
3n^2(n^2+7n+9)
Step-by-step explanation:
Find the common factor. In this case, it is 3n^2. Take out the common factor of the integers.
So, therefore it is
y = 50
Firstly, let's make an equation. We know that when y is 15, x is 3. Or, in other words, y is 5 times what x is. Therefore we can use the equation, y = 5x.
Now, just plug x into the equation.
y = 5(10)
it is a linear expression
10178.76
use formula:-2πrh+2πr^2
