i really need it i mean really i'm a freshman nd if i don't get this done by tomorrow im in serious trouble so please just please

Answer 4

i will give you a medal in everything you answer @UsukiDoll

Answer 5

what is it

Answer 6

Indicate which property is illustrated in Step 5.

Step 1 6x + 7 + 7x + 6 = (6x + 7) + (7x + 6)
Step 2 = 6x + (7 + 7x) + 6
Step 3 = 6x + (7x + 7) + 6
Step 4 = (6x + 7x) + (7 + 6)
Step 5 = (6 + 7)x + (7 + 6)
Step 6 = 13x + 13

Answer 7

O_O oh darn

Answer 8

Distributive property, I think.

Answer 9

it's either associative property or cumulative property or distributive property not sure

Answer 10

So it's .. factoring which ya maybe is called the Distributive Property (in reverse) or something..

Answer 11

what those two said...sorry that stuff was eons ago and may never be used again .

Answer 12

Indicate which property is illustrated in Step 6.

Step 1 9x + 9 + 11x + 9 = (9x + 9) + (11x + 9)
Step 2 = 9x + (9 + 11x) + 9
Step 3 = 9x + (11x + 9) + 9
Step 4 = (9x + 11x) + (9 + 9)
Step 5 = (9 + 11)x + (9 + 9)
Step 6 = 20x + 18

Answer 13

There is probably a property that says you can apply properties in reverse. They are usually rather thorough.

Actually, I think the symmetric property pretty much does say that.

Answer 14

distributive property

Answer 15

Anyway, that one is the "uh, addition actually works" property.
Additive property of equality? Or something.

Answer 16

arithmetic fact

Answer 17

There is some property that says "a = a" and the proof for it is probably 50 pages long and involves calculus.

Answer 18

Indicate which property is illustrated in Step 6.

Step 1 5 - 8x - 5 + 9x = (5 - 8x) + (-5 + 9x)
Step 2 = (5 - 8x) + (9x - 5)
Step 3 = 5 + (-8x + 9x) - 5
Step 4 = 5 + (-8 + 9)x - 5
Step 5 = 5 + x - 5
Step 6 = x + 5 - 5
Step 7 = x + 0
Step 8 = x

Answer 19

Additive inverse property, I think.

Answer 20

commutative
distributive
identity
associative

Answer 21

This is one of the ugliest web pages I have ever seen but it does have a nice list of properties: http://www.coolmath.com/prealgebra/06-properties/

Answer 22

Oh, commutative. I was looking at the wrong part. They're probably showing that 5 + x = x + 5.

Answer 23

Indicate which property is illustrated in Step 5.

Step 1 4x + 9 + 5x + 9 = (4x + 9) + (5x + 9)
Step 2 = 4x + (9 + 5x) + 9
Step 3 = 4x + (5x + 9) + 9
Step 4 = (4x + 5x) + (9 + 9)
Step 5 = (4 + 5)x + (9 + 9)
Step 6 = 9x + 18

Answer 24

We already did this one! You should know it.

Answer 25

@cassytaylor92 youre back

Answer 26

uhmm , yes :) @Starr_Dynasty

Answer 27

SACAPUNTUS - I believe that 50 page "proof" for something like 1+0 =1 is from the 3 volume Principia Mathematica by Bertrand Russell.

Answer 28

lol well thts gr8 @cassytaylor92
