I need help with this one?

Me find the missing dimension of a triangle height: 7 in., area: 21^2

Each equation given below describes a parabola. which statement best compares their graphs? x = 2y^2 x = 8y^2

Let f(x) = 3 − x . find the average rate of change of f(x) from x = a to x = a + h and simplify your answer so that no single factor of h is left in the denominator.
