The appropriate choice is
Polynomial B. -3x⁴ +5x³ +5
_____
C and D are not trinomials. (They have 4 terms, not 3.) A is 5th degree, not 4th.
Answer:
!.
Step-by-step explanation:
Use the Distance Formula:
Since we are talking about distance, we ONLY want the NON-NEGATIVE root.

Okay so a triangle has 3 vertices therefore 3 angles and 3 sides.
Let's first first the other angle not mentioned.
30+40=70 180-70=110
So the other angle is 110°.
If all the sides are different then this is an scalene triangle Kevin drew since the side and angle measurements are different. Scalene triangles have no equal sides or angles, everything is different!!

Answer:voy al
Step-by-step explanation:
I hope this helps you
cos^2 (x)+sin^2(x)=1
cos^2 (x)=1-sin^2 (x)
6.sin^2 (x)+2 (1-sin^2 (x))=5
6sin^2 (x)+2-4sin^2 (x)=5
2sin^2 (x)=3
sin^2 (x)=3/2
cos^2 (x)+3/2=1
cos^2 (x)=1-3/2
cos^2 (x)= -1/3
