Quadrilateral ghjk has vertices g(2, 3), h(8, 2), j(6, 8), and k(3, 6). it is transformed according to the rule t(–4, –5). what are the coordinates of g”? (–7, 3) (–2, 2) (–1, –7) (2, –2)

F(x)=x/2-2 and g(x)=2x^2+x-3 find (f+g)(x)

What is the simplified form of (3.25x10^3)(7.8x10^6) written in scientific notation?
