Answer:
C
Step-by-step explanation:
STR and QTP are both equal 180
so PTS +PTR=180 andQTR+PTR=180 which means
PTS=QTR(for a shorter explanation they are staying against each other in a line cross
11y-110=4y-5
7y=105
y=105:7
y=15 grafe which means
PTS
y*4-5=55 grade
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.

(2x - 5) (5x - 10)
Use FOIL
10x² - 20x - 25x + 50
10x² - 45x + 50
5( 2x² - 9x + 10)
2x -5
x -2
5(2x - 5)(x -2)
make each equal to 0
2x - 5 = 0
x - 2 = 0
2x - 5 = 0 x - 2 = 0
2x - 5 (+5) = 0 x - 2 (+2) = 0 (+2)
2x = 5 x = 2
x = 5/2
x = 5/2 , 2
