Hi S.L.

 

If you factor out the GCF (3 since 24=3*8 and 9=3*3, there is a 3 as a factor of both 24 and 9), you will be left with an expression that uses the distributive property.

 

24+9

 

3*8 + 3*3

 

3(8 + 3)

 

 

Notice:  24 + 9 = 33

and  3(8+3)=3(11)= 33

 

These two expressions are equivalent.
