Answer:

Step-by-step explanation:
To find the area of the inner circle, we need to find its radius. Here, we can write the radius as 4 - x. Now, we can use the formula
:
A =
* 
We can expand the square:
A = 
Thus, the polynomial is
.

Answer:
30 cm
Step-by-step explanation:
To find the perimeter of the rectangle, you first need to find the width and length of the rectangle:
54/9 = 6
L = 9
W = 6
The perimeter is 2lw:
The answer is 30 cm
Left side of angle W = 180 -95 = 85
1/3 of angle Y = 180 -85 -63 = 32
angle Y = 96
angle Z = 180 - 96 - 63 = 21
Answer:
Step-by-step explanation:
2b+8-5b+3=-13+8b-5 (combine like terms)
-3b + 11 = -18+8b ( switch sides)
+3b +11 = +18 +8b ( bold switches to other side)
11+18=8b+3b
29 = 11b
(divide each by 11)
b=2.636
