If you mean this:

then x = 0. The property in play here is the following: Any number raised to the "0" power is equal to "1". In this case, we would need to set the exponent of 3x = 0 and solve for x...
If you mean the equation:

then to solve for x(your blank), simply divide both sides of the equation by

:
You would have x =

this can also be written as

Answer:
293.776 yd
Step-by-step explanation:
3A=3L×w A=10×12.2=122
A=12.2×7.04=85.888
A=12.2×7.04=85.888
3A=122+85.888+85.888=293.776
Median of 10, 55, 34, 21
First we arrange number in ascending or descending
10, 21, 34, 55 in ascending.
Median is the middle number and this is between 21 and 34.
We find the average:
(21 + 34) /2 = 55/2 = 27.5
Median is 27.5.
