Answer:
3^(n+1) - 3^n / 3^(n-1) = 6
Answer:
110/289 feet
Step-by-step explanation:
Step one:
given data
Area of the floor= 55/14 square feet.
The length of the floor= 8 1/2 feet-----convert to simple fraction= 17/2 feet
Step two:
The expression for the area of the room is
Area= L*W
55/14= 17/2*W
55/14=17W/2
cross multiply
17W*14=55*2
289W=110
divide both sides by 289
W= 110/289 feet
For this case what is asked is to find the area of the window.
The area of the window in this case is a rectangle.
Therefore, the area is given by:
A = (18 * (1/12)) * (2)
A = 3 feet ^ 2
Answer:
the window is:
A = 3 feet ^ 2
