Which operation is NOT closed for polynomials? A) (x2 + 2x - 5) (x3 + 3x - 1) Penarai (x² + 2x - 5)(4x2 + 3x – 6). (2 + 2x - 5) + (2 - 5x + 1 (2x + 73 - 5) - (0 - 6x + 2)​

let m = monomial

let t = trinomial

so, m times t = t.

monomial times a trinomial = another trinomial.

38.6°

step-by-step explanation:

resultant is 10 pound

smaller force = 8 pound

angle formed = tan⁻¹(

                        =tan⁻¹(

                          =tan⁻¹(0.8)

                        =38.6°

i'm assuming that it's c.)   volcanoes built the mountains and earthquakes tore them down.
