Three-body decays of resonant states are studied using integral formulas for decay widths. The theoretical approach with a simplified Hamiltonian allows semianalytical treatment of the problem. The model is applied to decays of the first excited 3/2- state of 17Ne and the 3/2- ground state of 45Fe. The convergence of the three-body hyperspherical model calculations to the exact result for widths and energy distributions are studied. The theoretical results for 17Ne and 45Fe are updated, and uncertainties of the derived values are discussed in detail. Correlations for the decay of the 17Ne 3/2- state are also studied.
