If there are 5 specific spots and the order does matters then we would have:
11*9*8=792
Hope this helps!
The answer is 990 feet I just did the problem
Answer:
The perimeter of the room is 60 feet.
Step-by-step explanation:
If the area of the room is 224 square feet, and one side is 14 feet, then the other side is 224/14 feet, or 16 feet.
This gives us the dimensions of the room, 14 x 16.
From this, we can calculate the perimeter, which would be 2(14+16), or 60.

Answer:
Step-by-step explanation:
2x²-2x-12 = 2 (x²-x - 6)
but : x²-x - 6 = x² - 2(1/2)x +(1/2)² - (1/2)² - 6
= ( x - 1/2)² - 1/4 - 6
= ( x - 1/2)² - 25/4
x²-x - 6 = ( x - 1/2)² - (5/2)²
by identity ; a² - b² = (a - b ) ( a +b)
x²-x - 6 = ( x - 1/2 - 5/2) ( x - 1/2 +5/2)
x²-x - 6 = (x - 3) (x +2)
so : 2x²-2x-12 =2(x - 3) (x +2) = (2x-6)(x+2) .......(factored form)
now : 2x²-2x-12 = 0 : 2x - 6 = 0 or x+2 = 0
x= 3 or x = - 2 two solutions
