Answer: The width is 12 feet shorter than the length.
Step-by-step explanation:
The area of a rectangle can be calculated with this formula:
![A=lw](https://tex.z-dn.net/?f=A%3Dlw)
Where "l" is the lenght and "w" is the width of the rectangle.
We know that lenght of Jennie's yard is 30 feet, the width is
and the area is 540 square feet. Then:
![l=30\\w=(30-x)\\A=540](https://tex.z-dn.net/?f=l%3D30%5C%5Cw%3D%2830-x%29%5C%5CA%3D540)
Substitute these values into the formula and then solve for "x":
![A=lw\\\\540=30(30-x)\\\\540=900-30x\\\\30x=900-540\\\\x=\frac{360}{30}\\\\x=12](https://tex.z-dn.net/?f=A%3Dlw%5C%5C%5C%5C540%3D30%2830-x%29%5C%5C%5C%5C540%3D900-30x%5C%5C%5C%5C30x%3D900-540%5C%5C%5C%5Cx%3D%5Cfrac%7B360%7D%7B30%7D%5C%5C%5C%5Cx%3D12)
Therefore, the width is 12 feet shorter than the length.

Answer:
68% or 17/25
Step-by-step explanation:
100% - 32% = 68%
You could convert this to a fraction as 68/100 then simplify down to 17/25.
3 is correct. 4 is yes. 5 is no.
Because x+7=0 is -7
So substitute the number (-7) to (x^2+4x-24)
