How do i get a flat stomach in about 25 days?

First I would like to know if it would be possible for me to get a flat stomach in 25 days because I am 18 years old about 5’6 and about 120 pounds. I would also like to know if it would be possible for me to loose about 5-10 pounds? And what i could do to loose weight and get into better shape in 25 days preferably with a flat stomach??
