The smallest number would be 4
the three numbers would be 4, 10, and 14, which would have a sum of 28
Answer: 
Step-by-step explanation:
First, it is needed to determined the values for x = 1 and x = 2:

The sign change within the interval is the most sound evidence of the root existence. According to the Intermediate Value Theorem, there is a number
such that
. Another finding is that
is closer to 1 than to 2.
![c = a + \frac{b-a}{f(b)-f(a)}\cdot[f(c)-f(a)]](https://tex.z-dn.net/?f=c%20%3D%20a%20%2B%20%5Cfrac%7Bb-a%7D%7Bf%28b%29-f%28a%29%7D%5Ccdot%5Bf%28c%29-f%28a%29%5D)
![c = 1 + \frac{2-1}{4-(-1)}\cdot[0-(-1)] \\c = 1.2](https://tex.z-dn.net/?f=c%20%3D%201%20%2B%20%5Cfrac%7B2-1%7D%7B4-%28-1%29%7D%5Ccdot%5B0-%28-1%29%5D%20%5C%5Cc%20%3D%201.2)
X^2
diff. w.r. to x
=dx^2/dx
=2x^(2-1)
=2x .....
Answer:
x<-11/2
Step-by-step explanation
Try to isolate the variable by dividing it.
