"of" means multiply and "is" means equal
1.
x = 14
x = 14(3) <em>multiply both sides by 3 to isolate "x"</em>
x = 42
2.
x = 14
x = 14(5) <em>multiply both sides by 5 to isolate "x"</em>
x = 70
3.
x = 14
2x = 14(5) <em>multiply both sides by 5 </em>
2x = 70
x = 35 <em>divide both sides by 2 to isolate "x"</em>
4.
x = 14
7x = 14(8) <em>multiply both sides by 8 </em>
7x = 112
x = 16 <em>divide both sides by 7 to isolate "x"</em>
Answers: 42, 70, 35, 16

Step-by-step explanation:
The question has missing details; as the dimension of the cone is not given. I will give a general explanation on how to solve a question like this.
The space occupied implies that we calculate the volume of the cone.
The volume of 1 cone is:
![V_1 = \frac{1}{3}\pi r^2h](https://tex.z-dn.net/?f=V_1%20%3D%20%5Cfrac%7B1%7D%7B3%7D%5Cpi%20r%5E2h)
Since there are 5 cone trees, the total amount of space is:
![V =5 * V_1](https://tex.z-dn.net/?f=V%20%3D5%20%2A%20V_1)
![V = 5 * \frac{1}{3}\pi r^2h](https://tex.z-dn.net/?f=V%20%3D%205%20%2A%20%5Cfrac%7B1%7D%7B3%7D%5Cpi%20r%5E2h)
Assume the height and the radius of the cone tree are: 6cm and 7cm respectively.
The expression becomes
![V = 5 * \frac{1}{3} * 3.14 * 7^2 * 6](https://tex.z-dn.net/?f=V%20%3D%205%20%2A%20%5Cfrac%7B1%7D%7B3%7D%20%2A%203.14%20%2A%207%5E2%20%2A%206)
![V = 1538.6cm^3](https://tex.z-dn.net/?f=V%20%3D%201538.6cm%5E3)
Using the assumed dimensions, the amount of space occupied is ![1538.6cm^3](https://tex.z-dn.net/?f=1538.6cm%5E3)
Answer:
6.45ft
Step-by-step explanation:
17.5+4 3/4 or 4.75 = 22.25
22.25 + -15.8= 6.45ft
