Answer:
x = 11
Step-by-step explanation:
The diagonal creates two isosceles right triangles, so ...
m∠CBD = 45°
3x +12 = 45
3x = 33 . . . . . . subtract 12
x = 11 . . . . . . . . divide by 3
Suppose that some value, c, is a point of a local minimum point.
The theorem states that if a function f is differentiable at a point c of local extremum, then f'(c) = 0.
This implies that the function f is continuous over the given interval. So there must be some value h such that f(c + h) - f(c) >= 0, where h is some infinitesimally small quantity.
As h approaches 0 from the negative side, then:
![\frac{f(c + h) - f(c)}{h} \leq 0 \text{, where h is approaching 0 from the negative side}](https://tex.z-dn.net/?f=%5Cfrac%7Bf%28c%20%2B%20h%29%20-%20f%28c%29%7D%7Bh%7D%20%5Cleq%200%20%5Ctext%7B%2C%20where%20h%20is%20approaching%200%20from%20the%20negative%20side%7D)
As h approaches 0 from the positive side, then:
![\frac{f(c + h) - f(c)}{h} \geq 0](https://tex.z-dn.net/?f=%5Cfrac%7Bf%28c%20%2B%20h%29%20-%20f%28c%29%7D%7Bh%7D%20%5Cgeq%200)
Thus, f'(c) = 0
