If you draw an octagon (eight-sided polygon), select one vertex and construct each diagonal from this vertex, you will see there are 5 such diagonals. Thus, for each of the 8 vertices you can draw 5 diagonals and hence there can be 5 × 8 = 40 diagonals.

Step-by-step explanation:
We can equate the expression x^2+4x to f(x) and specify the variable of integration , the integrand and the symbol simply like this ,
Let,
Where the integrand is f(x) , x is the variable of integration , c is the constant of integration , and ∫ is the symbol of integration.
The derivate of what function is x^2 + 4x?
To find that out we integrate the function because Integrating a differentiate is the process of obtaining the original process because Integrals are also called as Anti-derivatives.
So,
This is an indefinite integral which would result in an addition of a constant later on because it does not have limits. The variable of integration is x because there is only one variable present in this expression so naturally the variable of concern is x
so now we solve,
Where K is the constant of the indefinite integral.
