Answer:
Step-by-step explanation:
Answer:
x = - 3
Step-by-step explanation:
2x - 10 + 6 = 7x - 7 - 2x + 12
2x - 4 = 5x + 5
- 5 - 4 = 5x - 2x
-9 = 3x
x = - 9/3
x = - 3
1, 0, -1 because past -1 would be 2
Working Formula:
V = s^3
Given:
dV/dt = -4 cubic meters per minute
V = 125 cubic meters
Required: ds/dt (rate of change of edge per minute) at V = 125 m^3
Solution:
Differentiate, equation below
V = s^3
dV/dt = 3*s^2 (ds/dt)
-4 = 3*s^2 (ds/dt)
ds/dt = -1.33/s^2 -----------> eq. (1)
V = s^3
(125)^0.33 = (s^3)^0.33
s = 5 ------------> eq. (2)
Substitute eq. (2) to eq. (1), we get
ds/dt = -1.33/(5)^2 = -0.053 meters per minute
<em>ANSWER: -0.053 meters per minute</em>
The greatest common factor of the three numbers is 4
