all those question marks

Answer 14

xD Refresh page

Answer 15

Just go to another page and come back to this one. It'll be fine. Just an Openstudy glitch that happens when you copy and paste signs.

Answer 16

use this for your question

Answer 17

wow lots of people viewing Cx

Answer 18

communitive property - changing the order of addition and multiplication doesn't change the answer

Answer 19

associative property - adding parenthesis to addition and multiplication doesn't change the answer

Answer 20

it is C

Answer 21

Answer 22

i can't see it

Answer 23

COMMUTATIVE PROPERTY---It does not matter which number is first when you write the problem.
examples...5+3=3+5, 9+7=7+9 or a+b = b+a or ab = ba
ASSOCIATIVE PROPERTY---Involves 3 or more numbers, two numbers are in parenthesis(they are "associated" together).
examples...(2+5) +4=11, 2+(5+4) = 11...remember,always do parenthesis first, order of operations. a+(b+c)=(a+b)+c or a(bc) = (ab)c
DISTRIBUTIVE PROPERTY---The sum of two numbers is equal to the sum of each addend times a third number.
examples..4 x (.6+3)= 4 x 6 + 4 x 3, 5x (1+2)= 5 x 1+ 5 x 2, a(b+c) = ab +ac or (b+c)a=ba + ca.
IDENTITY PROPERTIES---
1. addition--additive identity is 0. a+0=0+a = a
2. multiplication--multiplication identity is 1. a(1)=1(a)=a
INVERSE PROPERTIES--
1.additive inverse(or negative)...a + (-a) = 0
2. multiplication inverse (or reciprocal)...a (1/a)= (1/a)a = 1

If you look through these you will find that the answer to your question is commutative property.
