x=0 or x=4
just factorize basically
cancels the x’s so it’d be 3x-12=0 and from that x=4
The change in growth was 14 - 0.5 = 13.5 inches.
Since it is over the course of 5 weeks, divide 13.5 by 5.
13.5/5 = 2.7
2.7 = 270%
The rate of change was 270%. Hope this helps!

Answer:
The correct length is <em>34 feet</em>.
Step-by-step explanation:
Let us assume that the wall created is a rectangle <em>ABCD</em> as shown in the attached image.
We know that opposite sides of a rectangle are equal.
<em>Perimeter</em> of a <em>closed figure is calculated by adding all the sides of the figure</em>.
Here, from the figure, the perimeter is : AB + BC + CD + DA
AB and CD are equal to length.
BC and DA are equal to width.
So,
![Perimeter = 2 \times (length + width) ....... (1)](https://tex.z-dn.net/?f=Perimeter%20%3D%202%20%5Ctimes%20%28length%20%2B%20width%29%20.......%20%281%29)
Here, we are given that <em>perimeter </em>is 100 feet and <em>width</em> = 16 feet
Putting values in equation (1):
![100 = 2 \times (16 + length)\\\Rightarrow 50 = 16 + length \\\Rightarrow length = 34 feet](https://tex.z-dn.net/?f=100%20%3D%202%20%5Ctimes%20%2816%20%2B%20length%29%5C%5C%5CRightarrow%2050%20%3D%2016%20%2B%20length%20%5C%5C%5CRightarrow%20length%20%3D%2034%20feet)
Hence, length is 34 feet.
