$\int_{3}^{8}5xdx+\int_{3}^{8}-20dx$
Learn how to solve problems step by step online. Integrate the function 5x-20 from 3 to 8. Expand the integral \int_{3}^{8}\left(5x-20\right)dx into 2 integrals using the sum rule for integrals, to then solve each integral separately. The integral \int_{3}^{8}5xdx results in: \frac{275}{2}. The integral \int_{3}^{8}-20dx results in: -100. Gather the results of all integrals.
