-6z = 72
Divide both sides by -6
-6z = 72
/-6 /-6
z = -12
Answer:
Step-by-step explanation:
3 times 60 = 180 minutes
10 * 60 = 600 minutes
600/20 = 30 * 3 = 90 hours
The expression shown below is a difference of two squares.
<h3>Is a given expression a perfect square trinomial or a difference of two squares?</h3>
In this problem we have an algebraic expression that has to be checked by algebraic procedures. The complete procedure is shown below:
(x² + 8 · x + 16) · (x² - 8 · x + 16) Given
(x + 4)² · (x - 4)² Perfect square trinomial
[(x + 4) · (x - 4)] · [(x + 4) · (x - 4)] Definition of power / Associative and commutative property
(x² - 16)² Difference of squares / Definition of power / Result
The expression shown below is a difference of two squares.
