Find the surface area of the cylinder to the nearest tenth of a square unit. Use 3.14 for pi :))) thank you !!

Polynomial that can be factored as (3x-4)(3x+4)

Which statements describe the solutions to the inequality x< -20 check all that apply. there are infinite solutions. each solution is negative. each solution is positive. the solutions are both positive and negative. the solutions contain only integer values. the solutions contain rational number values.

State one method by which you can recognize a perfect square trinomial.
