i want full and right answers plz

not copying from another post solution

2)x" (width) by 20" (depth) No. 2 Western Cedars sawn lumber with notched supports is used to span 25ft, carrying an ASD load combination of (D+L+S). The dead load is a concentric load at the mid-span while the live and snow loads are uniform loads over a single span. Note, the beam is simply supported. Assume that D = 100 lbs, L = 200 lb/ft, and S=100 lb/ft. The beam is used in dry-service conditions (MC 5 19 %) and at normal temperature. The notches are 4 inch deep and sufficiently long to provide proper bearing length at the supports. Note that the self-weight of the beam is neglected and bending about strong axis is only considered. Show all calculations and assumptions for credits (20 point). Determine the minimum width (x) that can be adequate for the NDS requirements
