**Bella**, Sunday, February 22, 2009 at 8:45pmlike chopsticks said..multiply what's outside of the parenthesis with everything insidefor example

3. 1j + 2j + 12k

[ 1 j is just j ] add like terms

3j + 12k

4. 15ab + 45c

by the way, you're suppose to learn this stuff way before 9th grade..how are you learning it rite now?
