Answer: w^6/9
Step-by-step explanation:
first, i evaluated the powers.
3^-2 x 1 x 1/w^-6
then, i calculated those products.
3^-2/w^-6
then, i just expressed it with a positive exponent.
w^6/3^2
finally, i evaluated that.
w^6/9
Write an equation system by the problem
We can write "Area of rectangular balcony is 21 square feet" as
∴ area = 21
∴ l × w = 21 (<em>first equation)</em>
We can write "The perimeter is 20 feet" as
∴ perimeter = 20
∴ 2(l + w) = 20 <em />(<em>second equation</em>)
Simplify the second equation to find w in the value of l
2(l + w) = 20
l + w = 20/2
l + w = 10
w = 10 - l
Use subtitution method to solve the problem. Input w as (10 - l) to the first equation
l × w = 21
l × (10 - l) = 21
10l - l² = 21
-------------------- (multiply the two sides by -1)
l² - 10l = -21
l² - 10l + 21 = 0
(l - 7)(l - 3) = 0
l = 7 or l = 3
The length of the rectangle is either 7 or 3
Find the width
If the length of the rectangle is 7, then the width will be
w = 10 - l
w = 10 - 7
w = 3
The dimension will be 7 × 3
If the length of the rectangle is 3, then the width will be
w = 10 - l
w = 10 - 3
w = 7
The dimension will be 3 × 7
I think the probability would be onje half. (1/2)

Answer:
If DF is the angle bisector, that means that m∠ADF = m∠FDE so we can write:
9x - 1 = 8x + 3
x = 4°
