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.
Answer:
C. y = -x
Step-by-step explanation:
the slope is -1 so in the formula y= mx + b
b is 0 and m is -1
so plug it in and you get y = -x
Answer:
7 & 13
Step-by-step explanation:
Let the first number be x
2nd number = 8 less than 3 times the other
2nd number = 3x - 8
Their sum = 20
X + 3x - 8 = 20
4x -8 = 20
Collect like terms
4x = 20+8
4x = 28
Divide both sides by 4
4x/4 = 28/4
X = 7
First number = 7
2nd number = 3x - 8
= 3(7) - 8
= 21 -8
= 13.
Therefore the numbers are 7 and 13
