6y + 9

OR 

9 + 6y

300

Simplify the expression: 

3(2 + 4f) 

6 + 12f

OR 

12f + 6

400

Simplify the expression:

6(2y + 4) - 20

12y + 4

500

3x + 3

3(x + 1)

200

Factor the expression:

4x - 22

2(2x - 11) 

300

Factor the expression:

12y - 24

6(2y - 4)

400

6(y + 9)

500

Are the following expressions equivalent?

25x - 20

4.8x - 20 + 20.2x

Yes. The expressions are equivalent because the second expression simplifies to 25x - 20 if you combine like terms
