Solve each equation by finding square roots. 12: 5x2 80 15. 9x 25 = Solve each equation. 19. x + 6x + 9 = 1 18. Fitness A rectangular swimming pool is 6 ft deep. One side of the pool is 2.5 times longer than the other. The amount of water needed to fill the swimming pool is 2160 cubic feet. Find the dimensions of the pool. 16 9 25. 25x + 10x + 1 = 9 13. x-4 = 0 16. 3x-15 0 22. x + 8x + 16 = 14. 2x = 32 17. 5x2 40 = 0 20. x - 4x + 4 = 100 23. 4x2 + 4x + 1 = 49. 26. x-30x + 225 = 400 See Problem 1. See Problem 2. See Problem 3. 21. x2x + 1 = 4 24. x-12x + 36 = 25 27.9x2 + 24x + 16 = 36
