Book excerpt: We present measurements of branching fractions and charge asymmetries for charmless B-meson decays to three-body final states of charged pions and kaons. The analysis uses 81.8 fb[sup -1] of data collected at the[Upsilon](4S) resonance with the BABAR detector at the SLAC PEP-II asymmetric B Factory. We measure the branching fractions[Beta](B[sup+][yields][pi][sup+][pi][sup -][pi][sup+])= (10.9[+-] 3.3[+-] 1.6) x 10[sup -6], [Beta](B[sup+][yields] K[sup+][pi][sup -][pi][sup+])= (59.1[+-] 3.8[+-] 3.2) x 10[sup -6], and[Beta](B[sup+][yields] K[sup+]K[sup -]K[sup+])= (29.6[+-] 2.1[+-] 1.6) x 10[sup -6], and provide 90% C.L. upper limits for other decays. We observe no charge asymmetries for these modes.
