Simplify: 5(x - y) - (x - y) Question 2 options: x-y x+y 4x-4y 4x+4y
@Brookie105
I am not sure on this one
can you maybe Tag someone who could help with this one? because i have no idea.. :/
I would go with A, but I am not so sure.
ok ill go with a
i suppose.. if thats right
I am not sure..
what is 5-1?
What>?
if you have 5 apples and you take away 1 apple how many apples do you have?
are you able to take 1 away from 5? are do you need help with that?
5 take away 1 is just 4.... \[5-1=4 \\ \text{ so } 5(x-y)-1(x-y)=4(x-y) \\ \text{ now just use distributive property }\]
um..
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
i think its A x-y whatcha think?
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)
um.. sorry i had lost Wifi.. one sec
multiply all the terms inside the ( ) by 4... just like I did in the example
its either c or D i think more of C
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
