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 + 2x² + 4x + 8

• 4x³ + 6x² + 12x + 22

• 2x³ + 6x² + 28x + 8

• 4x³ + 2x² - 12x + 22

• 105x⁴ + 64x³ - 37x² - 16x

• 105x² + 64x³ - 15x² - 8x

• 105x⁴ - 15x² +8x

• 105x⁴ -37x² -16x
