Assuming that an exponentiation sign is missing, all you need to know is that rational exponents work like this:
So, you have
And similarly,
The formula for the area of a rectangle is:
w = width
l = length
First, we have to convert 2
into an improper fraction, then into a number. The improper fraction would be
. Let's convert that into a decimal.
Let's multiply
The area of the rectangle would be 25 feet!

The mean is the sum of all numbers divided by the number of numbers. We can set up an equation:
Where 'x' is the next quiz score she need. Solve for 'x'. Multiply 5 to both sides:
Add:
Subtract 322 to both sides:
So her next quiz score needs to be 73 in order to have a mean score of 79 on all her quizzes.
