4, -8
Step-by-step explanation:
Answer: 
Step-by-step explanation:
According to the product rule of derivatives.

The given function : 
here ,
and 
Differentiate both sides with respect to x, we get
and 
![[\because \dfrac{d(ax)}{dx}=a\ , \dfrac{d(a)}{dx}=0 \ \&\ \ \dfrac{d(x^n)}{dx}=nx^{n-1}]](https://tex.z-dn.net/?f=%5B%5Cbecause%20%5Cdfrac%7Bd%28ax%29%7D%7Bdx%7D%3Da%5C%20%2C%20%5Cdfrac%7Bd%28a%29%7D%7Bdx%7D%3D0%20%5C%20%5C%26%5C%20%5C%20%5Cdfrac%7Bd%28x%5En%29%7D%7Bdx%7D%3Dnx%5E%7Bn-1%7D%5D)
Then, Tge derivative of withe respect to x will be :




Hence, the derivative of the function is
.
Answer:
B=27
Step-by-step explanation:
4/3b-11=25
4B-33=75
4B=75+33
4b=108
B=27
Well, since the two triangles are congruent, angles DBC and ACB are equal to each other.
So, 30=4y + 2
Subtract 2, 28=4y
Divide by 4, 7 = y
Now since all angles in a triangle are equal to 180 you can do :
180 = (45 + 3x + 30)
Simplify, 180=3x +75
Subtract 75, 105 = 3x
Divide by 3, 35=x
