Can You Please Explain How To Do Problem #10? Thank you! :)

separate and square both the top and bottom

the square of square root three is just 3 and the square of  3 (the bottom of the fraction) is 9

so now you have 3(i^2) /9

you can simplify this by three  and then i^2 is -1

you now have -1/3 and thats the final answer

x-3y=4

step-by-step e

the formula for the equation of a circle is (x – h)2+ (y – k)2 = r2, where (h, k) represents the coordinates of the center of the circle, and r represents the radius of the circle. if a circle is tangent to the x-axis at (3,0), this means it touches the x-axis at that point.
