The answer is 61. you subtract 180-119=61
Answer:

Step-by-step explanation:
Data: Area of the room = 750 square feet
Width = Lenght - 5 feet
We have a rectangular room. To calculate it's area we do:
Area = Width x Length
We know that width depends on Lenght in this exercise. Replacing our data above:
750 square feet = (Length - 5 feet) x Lenght
Let's rearrange our equation. If we named Lenght = y :

Now we do one more final step to match one of the options:

If you look carefully, there are two more correct answers similar to the equation above:

Answer:
729
Step-by-step explanation:
You are multiplying 3 each time. The first 4 terms are given to you:
Term 1: 9
Term 2: 9 x 3 = 27
Term 3: 27 x 3 = 81
Term 4: 81 x 3 = 243
Term 5: 243 x 3 = 729
729 is the 5th term of the geometric sequence.
