First simplify the one inequality, 6r + 30 greater than or equal to 12 just divide by 6 then subtract 30 from both sides of the inequality. You should get r is greater than or equal to -3. For this one you need to reverse the inequality symbol then divide both sides by -1 to get a positive r, and you get r is less than -12. It's not A because there's two solutions, and it's not D for the same reason. It's not C because r isn't greater than -12. In conclusion it's B because it correctly represents the solutions that make the inequality true. I hope this helps you on your high school application :)
Answer:
400m of fencing is required to surround the area.
Step-by-step explanation:
First we need to find one side of the square. We know the area of a square is:
A = x²
We can use this information to find the length of a side of the square.
10000m² = x²
x = √10000m²
x = 100m
Now that we know what the length of the square yard is, we can calculate the perimeter. The perimeter of a square is:
P = 4x
For our problem:
P = 4(100m)
P = 400m
400m of fencing is required to surround the area.
