Interpret the following expression (5y^2-7)^3/(2y)^2

When you dilate a figure with a scale factor of 1/2, what will the dilated figure look like?                                                                                           a: the dilated figure will have side lengths that are half the length of the original side lengths.                                                                          b: the angles in the dilated figure will be half the measure of the original figure.                                                                                c: the dilated figure will have side lengths twice the length of the original.

Let f(x) = x + 2 and g(x) = x2 + 4. find f(g(f(
