Which could be the first step in solving the equation represented by the model below? 1) add 4 positive unit tiles to each side. 2) remove 4 unit tiles from each side. 3) add 6 positive unit tiles to each side. 4) remove 6 unit tiles from each side.

c

step-by-step explanation:

there is vertical asymptote at x = 2 and x = 0

vertical asymptote occurs at the points where the denominator is 0. so we can say that

x = 2 occurs when there is a factor (x-2) in the denominator, and

x = 0 occurs when there is a factor "x" in the denominator

thus, the denominator of the equation would have "x * (x-2)", this is option c only. that's the correct answer.

the answer is c: divide the arc's degree measure by 360°, then multiply by the circumference of the circle.
