integral from 1 to 8 of (3x+5)

Solution

\int_{1}^{8} (3 x + 5) d x

Solution

\frac{259}{2}

+1

Decimal

129.5

Solution steps

\int_{1}^{8} 3 x + 5 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}^{8} 3 x d x + \int_{1}^{8} 5 d x

\int_{1}^{8} 3 x d x = \frac{189}{2}

\int_{1}^{8} 5 d x = 35

= \frac{189}{2} + 35

Simplify

\frac{189}{2} + 35 : \frac{259}{2}

= \frac{259}{2}
