The names are triborane(9) and tetraborane(12).

Explanation:

The IUPAC rules for naming boron hydrides are:

  • Boron hydrides are called boranes, and the name of "BH"_3 is borane.
  • The number of boron atoms is indicated by an appropriate numerical prefix.
  • The number of hydrogen atoms is indicated by an Arabic numeral in parentheses immediately following the name.

∴ The names are triborane(9) and tetraborane(12).
