Step-by-step explanation:
27 is a perfect cube for
and 729 is a perfect cube for 
now you can pull out the numbers from under the root, for t (divide the exponent by 3)

now simply to 
Answer:
False
Step-by-step explanation:
Consider the equations with the same number of equations and variables as shown below,
<u>Case 1</u>

This equation has no solution because it is not possible to have two numbers that give a sum of 0 and 1 simultaneously.
<u>Case 2</u>

This equation has infinitely many possible solutions.
Therefore it is FALSE to say a linear system with the same number of equations and variables, must have a unique solution.

Answer:
$132
Step-by-step explanation:
40% off means it is actually 60% of the regular price.
Thus, you will multiply the original (220) by .6 (this means 60 percent)
and you will get 220*.6=132
We need to convert the equation of the circle to standard form only then we can find the radius and the center of the circle.

From this equation we can write:
Center of the circle is (-1,1) and the radius of the circle is 4.
