Answer:
Width is 10ft and length is 6ft.
Step-by-step explanation:
The area of a shape is the amount inside a shape. It is found using multiplication or A = l*w. Since the width is w and the length is 4ft less than its width or w - 4, use these expressions in the area formula to find their amount.
![A = l*w\\60 = w(w -4)\\60 = w^2-4w](https://tex.z-dn.net/?f=A%20%3D%20l%2Aw%5C%5C60%20%3D%20w%28w%20-4%29%5C%5C60%20%3D%20w%5E2-4w)
Subtract 60 from both sides and factor the quadratic to solve for w.
![w^2 -4w - 60 = 0\\(w-10)(w+6) = 0](https://tex.z-dn.net/?f=w%5E2%20-4w%20-%2060%20%3D%200%5C%5C%28w-10%29%28w%2B6%29%20%3D%200)
Set each factor equal to 0 and solve.
w - 10 = 0 so w = 10
w + 6 = 0 so w = -6.
Since w represents a length or distance it cannot be negative, this means the width is 10. The length which is w - 4ft is 10 -4 = 6. The length is 6 ft.

Step-by-step explanation:
< or > will give you an open dot which means it is not filled in.
≤ or ≥ will give you a closed dot which means it is filled in.
So for example number one:
x > 0 translated is x is greater than zero.
So look on the number line for an open dot on zero going toward the left (the side where the numbers get smaller). The rest are self explanatory.
