Answer:
x=13
Step-by-step explanation:
you have to isolate the variable
3(x-4)=x+14
distribute
3x-12=x+14
subtract 14 from each side
3x-26=x
subtract 3x from each side
-26=-2x
divide each side by -2
13=x
flip sides
x=13

Triangular prism and rectangular prism
Answer:
$2,700
Step-by-step explanation:
Let the width of the pasture be x, this means that the length of the pasture will be 2x
The area of a rectangle is L * B
Hence,
x * 2x = 18,000
2x^2 = 180,000
x^2 = 90000
x = 300 meters
This means the length is 600 metres
Now, to get the length of the fence, we need to know the actual perimeter which is 2(L + B)
= 2 ( 300 + 600)
2 * 900 = 1,800 metres
The cost is thus 1,800 * $1.50 = $2,700
