  We report results on the Dalitz analysis of three-body charmless B+=>K+Pi+Pi-
and B+=>K+K+K- decays based on a 140 fb$^{-1}$ data sample collected with the
Belle detector. Measurements of branching fractions for quasi-two-body decays
to scalar-pseudoscalar states: B+ => f0(980)K+, B+ => K*_0(1430)^0 Pi+, and to
vector-pseudoscalar states: B+ => K*(892)^0 Pi+, B+ => rho(770)K+, B+ =>
phi(1020)K+ are presented. Upper limits on decays to some pseudoscalar-tensor
final states are reported. We also report the measurement of the B+ => chi_c0
K+ branching fraction in two chi_c0 decays channels: chi_c0 => Pi+Pi- and
chi_c0 => K+K-.
