Assuming it is a Obtuse Scalene Triangle
Side a = 6
Side b = 15
Side c = 13.0767 = 3√19
The first answer and the last one
Plug in each number into their designated spots.
Example with (0,5)
0 goes into x and 5 goes into the y variable and this is the equation now:
2*0 +4*5=20
0 times 2 = 0 and 4*5=20
So that is one of the correct answers.
Repeat the process and you find that the last option is also correct.
C. we multiply the equation by 3
