5+2(3+2x)=x+3(x+1)
11=3
no real solution
A. is the answer llllllllllllllllllllllllllllll
Answer:It is $2 markup price.
Step-by-step explanation:
You can combine like terms
move the numbers around using associative property
n-5n+4-9
n=1n
1n-5n+4-9
1-5=-4 so
-4n-5

Answer: ![0.5x^7](https://tex.z-dn.net/?f=0.5x%5E7)
</h3>
This is the same as typing in 0.5x^7
Other equivalent forms are (1/2)x^7 or (x^7)/2
=====================================================
Work Shown:
![\frac{d}{dx}\left[f(x^2)\right] = x^8\\\\f'(x^2)*\frac{d}{dx}(x^2) = x^8\\\\f'(x^2)*2x = x^8\\\\f'(x^2) = \frac{x^8}{2x}\\\\f'(x^2) = \frac{x^7}{2}\\\\f'(x^2) = \frac{1}{2}x^7\\\\f'(x^2) = \boldsymbol{0.5x^7}\\\\](https://tex.z-dn.net/?f=%5Cfrac%7Bd%7D%7Bdx%7D%5Cleft%5Bf%28x%5E2%29%5Cright%5D%20%3D%20x%5E8%5C%5C%5C%5Cf%27%28x%5E2%29%2A%5Cfrac%7Bd%7D%7Bdx%7D%28x%5E2%29%20%3D%20x%5E8%5C%5C%5C%5Cf%27%28x%5E2%29%2A2x%20%3D%20x%5E8%5C%5C%5C%5Cf%27%28x%5E2%29%20%3D%20%5Cfrac%7Bx%5E8%7D%7B2x%7D%5C%5C%5C%5Cf%27%28x%5E2%29%20%3D%20%5Cfrac%7Bx%5E7%7D%7B2%7D%5C%5C%5C%5Cf%27%28x%5E2%29%20%3D%20%5Cfrac%7B1%7D%7B2%7Dx%5E7%5C%5C%5C%5Cf%27%28x%5E2%29%20%3D%20%5Cboldsymbol%7B0.5x%5E7%7D%5C%5C%5C%5C)
I used the chain rule on the second step. The chain rule will apply the derivative to the outer function f(x^2). Then we also apply the derivative to the inner function x^2 to get 2x, which is multiplied with f ' (x^2). From that point, we isolate f ' (x^2).
Side note: When applying the first derivative, it might help to think of f(x^2) as simply f(x) on a temporary basis.
