integral from 1 to 3 of 5x+4

Solution

\int_{1}^{3} 5 x + 4 d x

Solution

28

Solution steps

\int_{1}^{3} 5 x + 4 d x

Apply the Sum Rule:

\int f (x) \pm g (x) d x = \int f (x) d x \pm \int g (x) d x

= \int_{1}^{3} 5 x d x + \int_{1}^{3} 4 d x

\int_{1}^{3} 5 x d x = 20

\int_{1}^{3} 4 d x = 8

= 20 + 8

Simplify

= 28
