It looks like you want to find the short leg (x) of a right triangle with long leg 15 and hypotenuse 18. The Pythagorean theorem gives the relationship between the sides of a right triangle. 18² = 15² + x² 324 = 225 + x² x² = 324 - 225 = 99 x = √99 ≈ 9.9
Your answer would be C. x = 6, y = 5 This is because if you plug the numbers in to the inequality, we get: (4 × 5) ≥ (3 × 6) + 2 20 ≥ 18 + 2 20 ≥ 20 which is correct.
