My late response (haha): First, you would write a proportion.
Step 1: 2496 over 48 = x over 31
(x represents the area of the land that is not fenced).
Step 2: Cross multiply
2496 times 31 and x times 48
Step 3: Calculate
77376 = 48x
Step 4: Divide both sides by 48
77376/48 = 1612
48x/48 = x
Step 5: Write it as a sentence
The area of the land that is not fenced is 1612 squared meters.
Hope that helped! Good luck! :]
I believe the answer is A.

Answer:
- 4
- -2
- 4
- 2
- -2±√2
Step-by-step explanation:
In order to fill the first blank, we need to look at the second line to see what the coefficient of x is.
1. x² +<u> </u><u>4 </u>x +2 = 0
The constant is subtracted from both sides to get the second line.
2. x² +4x = <u> -2 </u>
The value that is added on the third line is the square of half the x-coefficient: (4/2)² = 4
3. x² +4x +<u> 4 </u> = -2 +4
On the fourth line, the left side is written as a square, and the right side is simplified. The square root is taken of both sides.
4. √(x +2)² = ±√<u> 2 </u>
Finally, 2 is subtracted from both sides to find the values of x.
5. x = <u> -2 ±√2 </u>
