Answer 1

Any ideas?

Answer 2

What are you being asked for? @reyna24

Answer 3

does that help?

Answer 4

@aysian97 that is the answer

Answer 5

@reyna24, do you want me to explain it to you?

Answer 6

thank you what about this one The perimeter of a rectangle is the sum of all of its sides. Write a mathematical expression for the perimeter of a rectangle with a length of 4 and a width of w. Simplify the expression if possible

Answer 8

sorry, @skullpatrol

Answer 9

@reyna24, would you like me to show you how i got that?

Answer 10

okay, so your trying to find the perimeter. In order to find the perimeter of a rectangle, you have to add up all the sides. Now you know that the length is 4, and if you have TWO side lengths then you have to multiply that by 2. so it would be 8. Now, you have the width. The question does not give you the width, so you just put a variable, "w".
Sooo, now you have "w" as the width. You have two widths, so the expression would look like, "2w". Now, you put it all together. p=8+2w. You don't have the value of "w", or the value of "p". Therefore, you can't go on. Does that make sense?

Answer 11

what about this one give an example of the commutative property of addition

Answer 12

okay, can you tell me what the commutative property of addition is? In your own words...

Answer 13

seee thing i dont no

Answer 14

okay let me give you the definition...and then you try and make an equation out of it.

Answer 15

can you do that?

Answer 16

okay here's the definition:
The Commutative Property of Addition states that changing the order of addends does not change the sum, i.e. if a and b are two real numbers, then a + b = b + a.
