Answer:
The answer is 153.68
Step-by-step explanation:
As long as
(or whichever function appears in the denominator) does not approach 0 as
,
![\displaystyle\lim_{x\to c}\frac{f(x)}{g(x)}=\frac{\lim\limits_{x\to c}f(x)}{\lim\limits_{x\to c}g(x)}](https://tex.z-dn.net/?f=%5Cdisplaystyle%5Clim_%7Bx%5Cto%20c%7D%5Cfrac%7Bf%28x%29%7D%7Bg%28x%29%7D%3D%5Cfrac%7B%5Clim%5Climits_%7Bx%5Cto%20c%7Df%28x%29%7D%7B%5Clim%5Climits_%7Bx%5Cto%20c%7Dg%28x%29%7D)
In this case,
![\displaystyle\lim_{x\to4}\frac gh(x)=\lim_{x\to4}\frac{g(x)}{h(x)}=\frac0{-2}=2](https://tex.z-dn.net/?f=%5Cdisplaystyle%5Clim_%7Bx%5Cto4%7D%5Cfrac%20gh%28x%29%3D%5Clim_%7Bx%5Cto4%7D%5Cfrac%7Bg%28x%29%7D%7Bh%28x%29%7D%3D%5Cfrac0%7B-2%7D%3D2)
so the answer is B.
Answer:
This means that the equations are equal to each other. We can therefore solve for x x x. Substitute the value of x x x in one of the equations (it does not matter which) and solve for y y y.
Step-by-step explanation:
Answer:
Solution given;
a⁴-23a²b²+b⁴
making in the form of a²+2ab+b²
a⁴+2a²b²+b⁴-2a²b²-23a²b²
(a²+b²)²-(5ab)²
factoring by using formula
x²-y²=(x+y)(x-y)
<u>(a²+5ab+b²)(a²-5ab+b²)</u>
