Answer:
It is Associative property :))
Step-by-step explanation:
361 congruent square tiles would be needed to cover the square shaped floor.
<h3>Equation</h3>
An equation is an expression that shows the relationship between two or more variables and numbers.
Since the number of tiles lying on both diagonals is 37. Let x represent the number of tiles on each side.
Counting one tile twice, there are:
- 37=2x-1
- x=19 tiles on each side.
19² = 361
361 congruent square tiles would be needed to cover the square shaped floor.

35
the ratio for the two is 5:7 and you want to find _:49. to get from 7 to 49 you multiply the 7 by 7. because you did that to one side you have to do the same to the other and multiply 5 by 7 which gives you 35
9: B right
10: C obtuse
11: B right
12: B right
I hope they are right! Sorry if they are not!
