What>?

if you have 5 apples and you take away 1 apple how many apples do you have?

11. freckles

are you able to take 1 away from 5? are do you need help with that?

12. freckles

5 take away 1 is just 4.... $5-1=4 \\ \text{ so } 5(x-y)-1(x-y)=4(x-y) \\ \text{ now just use distributive property }$

13. anonymous

um..

14. anonymous

can u tell me the answer and then explain.. or give me a exsample thats similar.. thats how i learn :D sorry if i seem like im being needy

distributive property goes like this: a(b+c)=a*b+a*c example 5(m+n)=5*m+5*n or can be written as 5m+5n

16. anonymous

i think its A x-y whatcha think?

17. freckles

did you actually try to use distributive property 4 doesn't equal 1... 5-1 is 4 not 1 5(x-y)-1(x-y)=4(x-y) just apply the distributive law to 4(x-y)

18. anonymous

um.. sorry i had lost Wifi.. one sec

19. freckles

multiply all the terms inside the ( ) by 4... just like I did in the example

20. anonymous

its either c or D i think more of C

21. freckles

4(x+y)=4x+4y 4(x-y)=4x-4y we had 4(x-y) so distributing 4 to the terms inside that ( ) gives 4x-4y not 4x+4y
