$\text{The domain}\\2x-6\neq0\ \wedge\ 6x-18\neq0\to x\neq3\\\\\dfrac{x^2}{2x-6}=\dfrac{9}{6x-18}\\\\\dfrac{x^2}{2(x-3)}=\dfrac{9}{6(x-3)}\ \ \ |\cdot6\\\\\dfrac{3x^2}{x-3}=\dfrac{9}{x-3}\iff3x^2=9\ \ \ |:3\\\\x^2=3\to x=\pm\sqrt3$

answer with explanation:

properties of numbers plotted on number line:

numbers on the right of number line is bigger.

the number that nicole wants to compare using number line

first plot these points on the number line, and real numbers on the right of number line is bigger than any real number on the left.

to plot , , on the number line, mark 3 lines between 1 and 2, equidistant from each other ,which we call and 2.

to plot, 1.5 on the number line, mark a line equidistant between 1 and 2.

you will find that, is on right of 1.5.so, is bigger than 1.5.

Nico wants to use a horizontal number line to compare 13 4 and 1.5. he is unsure how to do it and as
