The answer is 4 days. because if 2 people were digging a whole hole, it would take twice as long, being 8 days. digging half a hole, you would just cut the 8 in half, leaving 4 days for 2 people to dig half a hole.
C. The independent variable is s
Width = (7,6) - (7,3) = 3

Answer:
Width 15 feet
Step-by-step explanation:
Use formula

Let x feet be the width of the rectangle.
If the length of a rectangle is 4 times the width of the rectangle, then the length is 4x feet.
The area of the rectangle is 900 square feet, so
![900=x\cdot 4x\\ \\900=4x^2\\ \\x^2=225\ [\text{Divided by 4}]\\ \\x=\pm 15](https://tex.z-dn.net/?f=900%3Dx%5Ccdot%204x%5C%5C%20%5C%5C900%3D4x%5E2%5C%5C%20%5C%5Cx%5E2%3D225%5C%20%5B%5Ctext%7BDivided%20by%204%7D%5D%5C%5C%20%5C%5Cx%3D%5Cpm%2015)
The width cannot be negative, then x=15 feet and 4x=60 feet.
