Answer:
B. 2 boxes.
Step-by-step explanation:
Area of the floor = 7 1/2 * 8 5/6
= 15/2 * 53/6
= 265/4 feet^2.
Now we divide this are by 1 square foot giving a total of 265/4
= 66.25 tiles
so she needs 2 * 45 tiles boxes (answer).
Answer:√5 - √2
Step-by-step explanation:
= √(5 + 2 - 2√10 )
= √{(√5)² +(√2)² - 2.√5.√2}
= √(√5 - √2)² (by identity a² + b² -2ab = ( a-b)²)
= √5 - √2
5√5 = 11.8033989 or -2√5+7
