Idid all the other ones on my own accept the last 3 i did the last one in another question! i need just 2 questions !

19) 2(2g+1)

20) 5f+4s

Step-by-step explanation:

19) Look at the all options and distribute:

2(2g+1)

=4g+2

2(g+2)

=2g+4

4(g+2)

=4g+8

g(4+2)

=4g+8

The first option, 2(2g+1) is the only option that equals 4g+2

20) combine like terms, in this case 3f and 2f.

5f+4s

we cannot simplify anymore so that is the answer.

hope this helps :)
