Answer:
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.
I think the answer should be A correct me if I’m wrong tho
Simplifying
6r + 7 = 13 + 7r
Reorder the terms:
7 + 6r = 13 + 7r
Solving
7 + 6r = 13 + 7r
Solving for variable 'r'.
Move all terms containing r to the left, all other terms to the right.
Add '-7r' to each side of the equation.
7 + 6r + -7r = 13 + 7r + -7r
Combine like terms: 6r + -7r = -1r
7 + -1r = 13 + 7r + -7r
Combine like terms: 7r + -7r = 0
7 + -1r = 13 + 0
7 + -1r = 13
Add '-7' to each side of the equation.
7 + -7 + -1r = 13 + -7
Combine like terms: 7 + -7 = 0
0 + -1r = 13 + -7
-1r = 13 + -7
Combine like terms: 13 + -7 = 6
-1r = 6
Divide each side by '-1'.
