how would i rewrite the expressions 2(3+5) 12(4+7) 3(x+2) and 10(2+y+z) and how would i rewrite any expressions using the distributive property?? plz help thnx!!!

1.2*3+2*5=16 or 2*8
2.12*4+12*7=132 or12*11
3.3*x+3*2=3x+6
4.10*2+10*y+10*z=20+2y+2z

10(2+y+z) = 10*2 + 10*y + 10*z according to the distributive property.

Ok well i'll try my best to explain the distributive property. First as i'm reading your equation i notice that its one long chain. So take the 2 in front and multiply it through the whole equation then exculding the (6+10) multiply the 12 throught the whole equation and so on until the numbers out side the brackets are gone, next add the nubmers in the brackets then multiply them together with the other numbers in there brackets

The distributive property(of multiplication) means that
when each term in one factor is multiplied by each
term in the other factor and their results are added.
So in your example we get:
6+10, 48+84, 3x+6 and 20+10y+10z

#1 and #2 are designed to help you prove to yourself that the distributive property holds. #3 and #4 are to give you practice in using this property.
The property is generalized as follows:
a*(b+c) = a*b + a*c

artwork backwards... the traditional quantity being accelerated is 3. and the numbers being accelerated are 4.a million and 6.3 that are related by potential of a + sign. so, its 3(4.a million + 6.3) [they are related by potential of the addition sign interior the parenthesis via fact they have been related by potential of that interior the orignial equation] =]
