Answer: 8.3 feet
We know the area of 1 tile is:
(1)
We also know Jack used 103.75 tiles to cover the whole bathroom floor, which is a rectangle.
Remembering (1), we have that:
(2)
Which is also the area of the rectangle from which we only have the value of one of its sides, the width 
:
(3)
In addition, the area 
of a rectangle is given by the following equation:
(4)
Where 
is the length.
Substituting the value of the width written in (3) and the area (2) in equation (4):
(5)
We finally have the value of the length of the bathroom floor:
Garden one and two are both unknown, so I am choosing to call garden 2 X and then label garden 1 with comparisons to X.
It is tempting to list:
Garden Two = X
Garden One = X + 9
BUT there is an easier way. We are told that when 3 bushes are taken from garden 2 (x-3) and put in garden 1 (x + 12) then garden one has 1.5 times more than garden two.
Set it up like this:
1.5 ( x - 3) = x + 12 (because 1.5 times garden 2 will give us garden 1)
1.5x - 4.5 = x + 12 (Distribute)
.5x = 16.5 (Use subtraction to move variables to the right and other numb left)
x = 33 for Garden 2
33 + 9 for Garden 1 = 42
The range of the graph is would be (0,2)
AB = -2
CD = -1
BC = -3/-2
AD = -2/-3
I think it is d I think not sure tho
