Answer:
x = -5
Step-by-step explanation:
We can use the below formula to find the line of symmetry.
( x - a )² + b
Here,
line of symmetry = +a
Vertex = +b
And now let us take a look at the given equation.
y = x² + 10x + 22
To find the line of symmetry from the given equation we have to make the given equation as the given formula.
Let us use the completing square method for that.
y = x² + 10x + 22
<em>Put zero instead of y.</em>
x² + 10x + 22 = 0
x² + 10x = -22
x² + 10x + 25 = -22 + 25
( x + 5 )² = 3
( x + 5 )² -3 = 0
Therefore,
line of symmetry of the line is = -5
∴ x = -5
It is given that Joe was being exposed to an electromagnet shrinking machine. Because of this his height started decreasing .
Given,
The decrease was at a constant rate per second.
In 1.5sec, the height is decreased by 120cm.
So,
Variation per second =
Change in each second would be with negative sign indicate's decrease .
Hence, Answer is “-80” .
Hope it's helpful to you.

7. Its not properly visible sorry for this.
8. Its wrong
![(\frac{1}{3} ) {}^{2} = \frac{1}{9}](https://tex.z-dn.net/?f=%20%28%5Cfrac%7B1%7D%7B3%7D%20%29%20%7B%7D%5E%7B2%7D%20%20%3D%20%20%5Cfrac%7B1%7D%7B9%7D%20)
9. Right
10. Its wrong
![0.5 {}^{3} = 0.125](https://tex.z-dn.net/?f=0.5%20%7B%7D%5E%7B3%7D%20%20%3D%200.125)
11. Right
12. Its wrong.... Bcz square of minus is plus
![- 9 {}^{2} = 81](https://tex.z-dn.net/?f=%20-%209%20%7B%7D%5E%7B2%7D%20%20%3D%2081)
13. Right
14. According to the BODMAS rule..
![15 - 7 \times 2 + {2}^{3}](https://tex.z-dn.net/?f=15%20-%207%20%5Ctimes%202%20%2B%20%20%7B2%7D%5E%7B3%7D%20)
![15 - 14 + 8](https://tex.z-dn.net/?f=15%20-%2014%20%2B%208)

Split the shape into smaller shapes, (see attachment)
find the area of the split shapes. So first find the area of the triangles
A = 1/2bh
A = 1/2*2*3
A = 1/2*6
A = 3
so that is the area of one triangle. the area of the other is
A = 1/2*4*3
A = 1/2 * 12
A = 6
now find the area of the rectangle
A = l*w
A = 9*3
A = 27
add them all together
27 + 6+ 3 = 36
the area of the total figure is 36
