Using the area, the number of tiles needed to cover the floor is 6.
<h3>What is area?</h3>
The area is the region bounded by the shape of an object.
Therefore, the bathroom floor measures 3 yards by 3yards.
Hence the area of the bathroom floor can be calculated as follows;
area of the bathroom floor = 3 × 3
area of the bathroom floor = 9 yards²
The area of the custom tiles that makes the flooring is 1 1 /2 square yards.
Hence,
number of tiles needed to cover the floor = 9 ÷ 3 /2
number of tiles needed to cover the floor = 9 × 2 / 3
number of tiles needed to cover the floor = 18 / 3
number of tiles needed to cover the floor = 6

Step-by-step explanation:
Answer:
x = 15
Step-by-step explanation:
FD and AC are parallel because both are perpendicular to EB. Angle EDF and Angle DCA are congruent because they are corresponding angles. The measure of Angle DCA is also 3x because congruent angles have the same measure.
Now consider Triangle ACD. Because the sum of all three measures of the angles in a triangle add up to 180°.
x + 8x + 3x = 180°
12x = 180°
12x/12 = 180/12
x = 15
You can see how the difference between two consecutive terms is constantly increasing:
So, for the next terms we'll have to add +9, +11, +13 and so on.
Also, note that 
is obtained by adding the 2nd odd number to 
, 
is obtained by adding the 3rd odd number to , and so on.
So, the recursive formula is
For the explicit formula, recall that the sum of the first n odd numbers is n squared. Taking into account the fact that we're not starting from 1, we have
