Given that Jessica is a custodian at Oracle Arena.
She waxes 20 square meters space of the floor in 5/3 of an hour. Jessica waxes the floor at a constant rate means rate will remain fixed for any hour.
Now we have to find about how many square meters can she wax per hour.
To find that we just need to divide 20 squaer meters by 5/3 hours



=12
Hence final answer is 12 square meters can she wax per hour.
Which can also be written as
per hour.
Given:
The given equation is

To find:
All the real solutions.
Solution:
We have,

It can be written as


Using zero product property, we get
and 
and 
and 
We know that
is an imaginary number because there is a negative sign under the square root.
Therefore,
is the only real solution of the given equation.
