You have to multiply by the complex conjugate so that you can clear the radical from the denominator.
Once you do the multiplication simplify the radical. There's still a common factor in -54, -18, & 75 so divide all those by 3.
Answer:
C. 60
Step-by-step explanation:
From triangle ADB,
From triangle ADC,
The perimeter is the distance around the figure.
The perimeter
When you plot the points and use the vertical line test, you'll see that none of the vertical lines go through two points. Therefore verifying that this set of points represents a function.
You do 24/4= 6
You divide I hope this helps
I think it that but if not I am sorry good luck
