The given mathematical expression <span>2 (c+7)=2c+14 is an example is</span> an example of Distributive Property.
We can examine the given problem, we have 2(c+7) where 2 can be distributed to both c and 7. Then the result of distribution is 2c and 14 which the same in the opposite side.
Answer:
f(x) = 6 x^2 - 1
f(2) = 6 * 2^2 - 1 = 23
f(-1) = 6 * -1^2 - 1 = 6 * 1 - 1 = 5
f(2) - f(-1) = 23 - 5 = 18
![0=65892.56\cdot x^{-1.67}](https://tex.z-dn.net/?f=0%3D65892.56%5Ccdot%20x%5E%7B-1.67%7D)
It would seem the only solution is 0, but
![x^{-1.67}=\frac{1}{x^{1.67}}](https://tex.z-dn.net/?f=x%5E%7B-1.67%7D%3D%5Cfrac%7B1%7D%7Bx%5E%7B1.67%7D%7D)
and the denominator of the fraction can't be equal zero, therefore there's no solution.
C. x = 7
1 + 3 * x = 22
1 + 3x = 22
Subtract 1 from both sides.
3x = 21
Divide both sides by 3.
x = 7
