Convert to vertex form:-
f(x) = 4(x^2 + 2x) + 7
= 4[(x + 1)^2 - 1] + 7
= 4(x + 1)^2 + 3
The axis will be the vertical line x = -1
Answer:
conclusion because you are concluding eveything you said in the paragraph before.
Answer:
<h2>
X= 6°</h2><h2>
z= 112°</h2>
Solution,
Finding the value of X,
![11x + 2 = 68](https://tex.z-dn.net/?f=11x%20%2B%202%20%3D%2068)
( being vertically opposite angles)
![11x = 68 - 2 \\ 11x = 66 \\ x = \frac{66}{11} \\ x = 6](https://tex.z-dn.net/?f=11x%20%3D%2068%20-%202%20%5C%5C%2011x%20%3D%2066%20%5C%5C%20x%20%3D%20%20%5Cfrac%7B66%7D%7B11%7D%20%20%5C%5C%20x%20%3D%206)
Value of X is 6
Now, finding the value of z
![z + 68 = 180](https://tex.z-dn.net/?f=z%20%2B%2068%20%3D%20180)
(sum of angle in linear pair)
![z = 180 - 68 \\ z = 112](https://tex.z-dn.net/?f=z%20%3D%20180%20-%2068%20%5C%5C%20z%20%3D%20112)
Value of z is 112.
Hope this helps....
Good luck on your assignment...
