Let's say that ground level is 0. When she goes down to the basement, she is going -12 feet since each flight of stairs is12 feet. Then she goes up 12 more feet= -12+12=0. She is back at ground level. Then she goes up another 12 feet= 0+12= 12. So I believe the answer is 12 feet.

Associative property of (21)(7)(3x) ? <br> PLEASE HELPPPP <br> 40 PTS!!!!
sdas [7]
Ehh, now it's letting me answer.

So the associative property is basically as long as it's addition or multiplication,  you can move around the groupings and it will still be the same.

For example, you can say:(21 * 7) (3x)  instead of (21)(7)(3x)

And it would be equal to the old version.

(To answer your other question, the commutative property is you can move around all the parts of the equation as long as it's addition or multiplication.)

So basically, it would be the first one you sent me.

Step-by-step explanation:

Add all the numbers together(36), and then see how many out of that number are the vibrant blue shirt. Since they are asking the probability of you being given a vibrant blue shirt, and there are 11 out of the 36 shirts, therefore you have an 11/36 chance that you will be given a vibrant blue shirt.
