What is the total surface area of this square pyramid?

Triangles abc and dfg are given. find the lengths of all other sides of these triangles if: b ∠a≅∠d, ab·dg=ac·df, ac=7 cm, bc=15 cm, fg=20 cm, and df-ab=3 cm.

Find the inverse of each function for problems 1–6. state the domain and range of both the function and its inverse. restrict the domain of the function if needed. f(x) = –x2
