Answer:
Step-by-step explanation:
The associative property states that you can add or multiply regardless of how the numbers are grouped. By 'grouped' we mean 'how you use parenthesis'. In other words, if you are adding or multiplying it does not matter where you put the parenthesis. Add some parenthesis any where you like.
What we know:
Perimeter=60
Perimeter formula=2l+2w
l=2w
This perimeter has the following set up using p=60 and l=2w:
perimeter =2(l)+2w
60=2(2w)+2w
60=4w+2w
60=6w
Now that we know how many w's we need to have we can use this information to find which equations have 6 w's and which one does not.
Look at the first equation:
2(2w+w)=60 distributive power
4w+2w=60 like terms
6w=60 correct
second equation:
w+2w+w+2w=60
6w=60 like terms, correct
third equation:
2w+2x2w=60 multiplication property
2w+4w=60 like terms
6w=60 correct
fourth equation:
w+2w=60 like terms
3w=60 not correct
Fourth equation is not correct.
Answer:

Step-by-step explanation:
Answer:
- 310.5/100
Step-by-step explanation:
To find the length of each side 72/4
Each side is 18
So area is 18 times 18= 324
