The correct answer is option 4: 
Step-by-step explanation:
Given expression is:

The associative property states that for any three terms that are being multiplied, different order of multiplication (i.e. which two terms are multiplied first) will give the same answer.
Let a,b and c be the three terms
then

So applying the associative property on given expression

Hence,
The correct answer is option 4:

The value of seven is in the thousands place and is 10 time the number seven if it were at the hundreds place, which is where 2 is.
7000=10 x 700
7000=7000

Answer:
It would be B!
Step-by-step explanation:
D has an obtuse angle, so it can be eliminated.
C has angles that are not vertical, but rather adjacent. Same goes for A!
Hope this helps!
because the denominator is on the bottom, you have to find a number which both 12 and 9 can be divided by. In this case the only answer that isn't a decimal is 3
