You can use permutations when order matters and use combinations when order doesn’t matter.
Answer:
it would take about 11 to 13 days
Step-by-step explanation:
AC= sqrt(AB^2 -BC^2)
=sqrt(75^2 - 72^2)
AC=21
Answer is 21
The equivalent equation of the quadratic equation (x² – 1)² – 11(x² – 1) + 24 = 0 is u² - 11² + 24 = 0
<h3>How to determine the equivalent equation?</h3>
The equation is given as:
(x² – 1)² – 11(x² – 1) + 24 = 0
Let u = x² - 1
So, we have:
u² - 11² + 24 = 0
Hence, the equivalent equation of the quadratic equation (x² – 1)² – 11(x² – 1) + 24 = 0 is u² - 11² + 24 = 0
