^{The perimeter of the
 triangle is 10x+20. Find the length of the missing side}

• 6x+10

• 15x+30

• 5x+10

• 5x-10

The perimeter of the triangle is 3x³ + 4x² + 8x + 15. If the shortest side is 2x² + 12x, the longest side (the hypotenuse) is x³ - 8x + 7, then what is the missing side length?

• 2x³ + 6x² + 28x + 8

• 2x³ + 2x² + 4x + 8

• 4x³ + 6x² + 12x + 22

• 4x³ + 2x² + 12x + 22
