answer:

This triangular prism calculator determines the volume and surface area of that solid. ... identical two bases; three rectangular faces (right prism) or in parallelogram shape (oblique prism); the same cross section along its whole length ... Length * Triangular base area given two angles and a side between them (ASA).

Step-by-step explanation:

idk but i found this "the graph of y = f(x-2) is the graph of y = f(x) translated two units rightward.
