The question is missing the figure. So, it is attached below.
Answer:
Area of the shaded sector is <u>144π units squared</u>.
Step-by-step explanation:
Given:
Central angle of the sector is, 
Radius of the circle is, 
We know that, area of a sector of a circle of radius 'R' and central angle
is given as:

Plug in
. This gives,

Therefore, the area of the shaded sector is 144π units squared.
5x - 2x + 8 = 2 + 6x + 6
Add like terms:
5x - 2x = 3x
2 + 6 = 8
3x + 8 = 6x + 8
To isolate the variable, subtract 6x from both sides of the equation:
3x - 6x = -3x
-3x + 8 = 8
Now subtract 8 from both sides:
8 - 8 = 0
-3x = 0
To finish, divide both sides by -3:
0 ÷ -3x = 0
The answer is x = 0
Hope this helps.
Answer:
W = - 14
Step-by-step explanation:
13W - 2(4W + 1) = W - 58
13W - 8W - 2 = W - 58
13W - 8W - W = 2 - 58
4W = - 56
W = - 56 : 4
W = - 14
What do you mean? At first it was 4 times as old, then it's twice her age?
It would be 90%. 18 is 90% of 20
