Answer:
-5
Step-by-step explanation:
First, distribute the 2 to the 3, -9, and 5. You will get 6 + 6 - 18 + 10 + (-9). Then, you can start from the beginning and work through combining the terms. The original equation is in bold after every step.
6 + 6 - 18 + 10 + (-9)
6+6 = 12
12 - 18 + 10 + (-9)
12-18 = -6
- 6 + 10 + (-9)
-6 + 10 = 4
4 + (-9)
4 - 9 = -5

simple room measurement
Measure the length using the distance from one wall to the opposite wall.
Measure the width from wall to wall.
Add 2 to 4 inches to each side. This accounts for waste, doors and slanting walls. It’s easy to cut a little off for a perfect fit, but it’s impossible to add without creating unsightly seams.
Multiply the length times the width or enter those into the calculator above. This is your total square footage for that room.
Repeat this process for each room.
