Answer:
-1/18
Step-by-step explanation:
Let's multiply left and right by 3n:
2 = -12 * 3n =>
-36n = 2
now divide by -36:
n = 2/-36 = -1/18
Answer:
190 cm2.
Step-by-step explanation:
First you have to find the area of the whole shape.
20 cm times 10 cm is 200 cm2.
Now, you have to find the area of the smaller shape inside.
5 cm times 2 cm = 10 cm2.
Finally, you subtract the area of the smaller shape from the larger shape to find the area of the shaded area.
200 cm2 - 10 cm2 = 190 cm2.
Answer:
15
Step-by-step explanation:
10% of 12 =1.2
1.2*2= 2.4 (20%)
1.2/2= 0.6 (5%)
2.4+0.6= 3
12+3= $15
- g(x)=|-x+2|(attachment 1)
f(x) is a quadratic function having roots 1,-3
For function creation of f(x) visit attachment 2
Now
![\\ \sf\longmapsto f(-2)=(-2)^2+2(-2)-3=4-4-3=-3](https://tex.z-dn.net/?f=%5C%5C%20%5Csf%5Clongmapsto%20f%28-2%29%3D%28-2%29%5E2%2B2%28-2%29-3%3D4-4-3%3D-3)
![\\ \sf\longmapsto g(-2)=|-(-2)+2|+|2+2|=|4|=4](https://tex.z-dn.net/?f=%5C%5C%20%5Csf%5Clongmapsto%20g%28-2%29%3D%7C-%28-2%29%2B2%7C%2B%7C2%2B2%7C%3D%7C4%7C%3D4)
Hence
![\\ \sf\longmapsto (f+g)(-2)](https://tex.z-dn.net/?f=%5C%5C%20%5Csf%5Clongmapsto%20%28f%2Bg%29%28-2%29)

![\\ \sf\longmapsto -3+4](https://tex.z-dn.net/?f=%5C%5C%20%5Csf%5Clongmapsto%20-3%2B4)
