Hey could someone help?

Express in the simplest form: (x^2+9x+14/x^2-49) / (3x+6/x^2+x-56)

List the sides of δrst in ascending order (shortest to longest) if: m∠r =x+28°, m∠s = 2x+16°, and m∠t = x+12

Rewrite the following quadratic functions in intercept or factored form. show your work. y = x^2 + 7x + 10
