To find the length of the side of a square when the area is known, find the square root of the area:
Side length = √729
Side Length = 27 feet.
The standard form of an equation is

In the question, we have the following formula

To get the formula in standard form, we first have to subtract 2y from both sides (since we need to get 2y on the left side)

Finally we subtract 1 from both sides (since we need the number on the right side)

Hence, 4. is the correct answer.
Answer:
2
Step-by-step explanation:
1. 20/10
2. divide numerator and denominator by 10
2. 2/1 = 2
Actual length of the room
6 * 40
240 inches
Actual width of the room
4 * 40
160 inches
Area of the room
240 * 160
38400 inches^2

Have a great rest of a brainly day!
The mean is 10.
To find the mean you add up all the numbers and divide by how many sets of numbers there were.
8+10+11+8+13=50
50/5=10.
