Can someone help? I will rate you as helpful(: thank you

Use the definite integral to find the area between the x-axis and f(x) over the indicated interval. Check first to see if the graph crosses the x-axis in the given interval. f(x) = 48 - 3x ; [0,8] Set up the integral (or integrals) needed to compute this area. Use the smallest possible number of integrals. Select the correct choice below and fill in the answer boxes to complete your choice. O A. dx + dx O B dx 0 O c. dx + dx For the interval [0,8], the area between the x-axis and f(x) is (Type an integer or a simplified fraction.)
