2x^2-8
The ^ means to the power of so basically 2x is squared
If you could show a diagram of some sort, or explain it, it would help but from how i understand it:
you can use either the Sin() Tan() or Cos() function. for example:
Sin(45)= The side opposite to the angle/ the hypotenuse
Cos(45)= side Adjacent to the angle/ the hypotenuse
Tan(45)= Opposite side to the angle/ side adjacent to the angle
Look at which side you need to find, and fill in the 84.6 where you need to. If you need hep with that please tell me. :)
The two angles are adjacent on a straight line so they are supplementary. Thus 8x+5+13x-14=180
21x-9=180
21x=189
x=9

Answer:
The last graph
Step-by-step explanation:
This is because when there is a greater than sign, the line on the graph is dotted and the shaded area is facing upwards. I try to remember that when there is a greater than sign or a greater than or equal to sign, the shaded area faces up towards the sky.
Hope this helps. Please inform me if my answer is wrong.
