Question 433569
"Use the commutative law of multiplication to write an equivalent expression. 
4(a + b)" 


Commutative means you can move it around and not change the outcome.


Such as 2 x 4 is the same as 4 x 2


In this case:
4(a + b)
= (a + b)4 {moved the 4 to the back without changing the result}
