You can't convert miles into gallons those are two different units of measurement.
The median is 19.5. 16+23 is 39. 39/2 is 19.5
P^-4 x -5p
In properties of exponents, if the exponent is negative then you move the variable with the negative exponent to the denominators place and it changes to positive and the numerator becomes 1.
p^-4=1/(p^4)
Also, if no exponent is present it is understood to be 1.
Keeping this in mind,
p^-4 x -5p
1/(p^4) x -5p^1 substituted p^-4 by 1/p^4 and added ^1 to -5p
-5p^1/p^4 multiplied-5p^1 to 1
-5/p^3 simplified
Cube has 6 faces/planes :)
You can pick any of them it won’t hold it against you.
I do it all the time.
Have a good day
