Answer:
this trinomial is prime, and cannot be factored.
Step-by-step explanation:
when expanding the equation, you multiply the last term by the first term's coefficient, and then find two factors that multiply to that product, and sum to the middle coefficient.
1 * 19 = 19
there are no factors that will multiply to 19 and sum to 11. thus, this polynomial is prime.

-r+5<-3
Step-by-step explanation:
plug in 19 to the equation inequality
Answer:
Below in bold.
Step-by-step explanation:
300 degrees - reference angle is |360 - 300 |= 60 degrees
225 = 225 - 180 = 45 degrees
480 = 480 - 360 = 120 so it is 180 - 120 = 60 degrees.
-210 = |-210 + 180| = 30 degrees.
