Can you combine like terms without formally showing the distributive property? Explain.

Yes you can! Say you have 5(2 + x) + 3x. The answer would be 10+8x because when you use the distributive property you will end up getting 5*2 5*x and once you multiply, it's obvious 5 times 2 is 10 and 5 times x will equal 5x. Then you add 5x and 3x and get 8x. So, the simplified expression here is 10+8x. When you have this as an answer it's proving your answer right. You can without using the distributive property. We can have 10+5x+3x and it will be your simplified expression. It's the same thing with equations too.

Leno4ka [110]

$102,105-$100,000= $2105

$2105/10 =$210.5

1000*.07*.5= $3500

3500- 210.5 = $3289.5

So in my estimation, it is $3,318.41

Which expression gives the unit length of the line segment with the endpoints (-12, 8) and (2, 8)

Mashcka [7]

They have the same y coordinate, 8, so all we need to figure out is the distance between -12 and 2 of this horizontal line.
to do this add 12 and 2, you should get 14.
now using this information, find the expression that is equal to 14.
|-12|+|2|=14
|-12|-|2|=10
|8|+|8|=16
|8|-|8|=0
as we can see, the first expression would be the correct one.
