You must use Pythagorean theorem, which is
a and b are both legs (the two legs are the sides that form a perpendicular right angle) while c is the hypotenuse (side opposite the right angle)
In this case...
a = y
b = 8
c = 12
^^^Plug these numbers into Pythagorean theorem
Simplify as much as possible
+ 64 = 144
Isolate y by subtracting 64 to both sides
+ (64 - 64) = 144 - 64
= 80
Further isolate y by taking the square root of both sides. This will take away the square from the left side
y =
<<< Can be further simplified
4√5 = y

Answer:
x=2
Step-by-step explanation:
5x−1=2x+5(Possibility 1)
5x−1−2x=2x+5−2x(Subtract 2x from both sides)
3x−1=5
3x−1+1=5+1(Add 1 to both sides)
3x=6
3x
3
=
6
3
(Divide both sides by 3)
If the pond were a rectangle, then:
length=15 m
width=6 m
We would have to calculate the perimeter of this rectangle.
Perimeter of a rectangle=2(length)+2(width)
Perimeter of this rectangle=2(15 m)+2(6 m)=30 m+12 m=42 m
We need 42 m and I only have 40 m, therefore, it would not be enough for fencing the pond.
