I guess you want to find the 4 numbers

x + x + 2 + x + 4 + x + 6 = -28
4x + 12 = - 28
4x =  - 40
x = -10

Answer:

Width - 12ft  Length - 30ft

Step-by-step explanation:

Width is 12ft

Length is 30ft

Depth is 6ft

The length, 30ft, is 2.5 times longer than the width which is 12 ft which confirms the two dimensions to be correct.

When you multiply all three of the dimensions of the swimming pool you will get 2940 cubic feet

(4/9)^-1=<br><br><br>A. -4/9<br><br>B. 9/4<br><br>C. -9/4
Romashka-Z-Leto [24]

Answer: 9/4

Step-by-step explanation: Think of (\frac{4}{9})^{-1}as \frac{4^{-1} }{9^{-1}}.

Now, we can change 4⁻¹ to 4¹ by moving it to the denominator and

we can change 9⁻¹ to 9¹ by moving it to the numerator.

So we have 9¹/4¹ which simplifies to 9/4.
