Answer 1

well just distribute the number outside the paratheses to the stuff inside it.

1.3u + 3v
2.8+20s+3=22+20s
add like terms

you try it from here

Answer 2

oh sorry its

8+20s+3=11+20s

silly me

Answer 3

like 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
