Question

Please someone help me

Answer 1

1)
2(3x-5)
Use the distributive property.
2(3x)+2(-5)
6x-10 
That is not equal to 6x-8.

2)
2-2+5x
Simplify the like terms, 2 and -2
Add them together, 0
5x=5x the two expressions are equal

3)
2x+8 because there are x stickers in a pack
2(4+x)=2(4)+2(x)=8+2x=2x+8
Yes they are the same expressions.

Answer 2

6x-8:2(3x-5)
we can start will using the destibutive property on the parenthasis
2 times 3x = 6x and 2 times 5 is 10
so 6x-8:6x-10
since there is a 6x on both sides we can cancel it out and we are left with -8:-10
so the first on is not eqivilant.

2-2+5x;5x
for this one we have a 2-2 which we can do
2-2=0 so we are left with 5x:5x
this one is eqivialant.

for the third one since she baught two packs of stickers and we don't know how many stickers are in each one we can use x to reprezent the number of stickers.
so 2x for the packages and then +8 for the individual
2x+8:2(4+x)
again we can use the distrubutve property
2 times 4 and 2 times x
2x+8:8+2x.
and we have the same thing on both sides so the are equivalant
