Answer:
{2, 3, √13}
Step-by-step explanation:
In a right triangle, the sum of the squares of the two shorter sides equals the square of the third side (Pythagoras).
Let's check each set of sides in turn.
A. {2, 3, √13}
2² + 3² = 4 + 9 = 13
(√13)² = 13
This is a right triangle.
B. {5, 5, 2, √10}
This is a quadrilateral (four sides).
C. {5, 12, 15}
5² + 12² = 25 +144 = 169
15² = 225
This is not a right triangle.
Answer:
see below
Step-by-step explanation:
-2x^4-x^3+8x^2-12
First list by highest power to lowest power
The highest power is x^4 so this is a 4th degree polynomial or a quartic polynomial
If you really mean the multiply sign
-2x^4-x^3*8x^2-12
-2x^4 - 8x^5 -12
-8x^5 -2x^4 -12
This would be a 5th degree or quintic
(4,3) you add 5 to the x and subtract 3 from y
