Geometry help please. Complete the similarity statement, in the box below, of these two triangles.

Which graph corresponds to the function f(x) = x2 + 4x – 1?

F(x) = 1/x g(x)=x-4 can you evaluate (g*f)(0) ? why or why not?

Find the perimeter of the triangle with vertices  d(3, 4),  e(8, 7), and  f(5, 9). do not round before calculating the perimeter. after calculating the perimeter, round your answer to the nearest tenth.
