Answer:
Indeed, the equation is solvable by factoring. By applying the given equation, you can take the square root of both sides. Since both 169 and 9 are perfect squares, the left-hand side simplifies to plus or minus 13/3, producing rational results. Adding 6 to 13/3 yields a rational number while subtracting it does too. Thus, a quadratic equation is factorable if its solutions are rational.
In this situation, we start with the following equation: To isolate the value of y, we follow these steps: First, we subtract 6 from both sides of the equation: Second, we take away "y" from each side: Third, we add

to both sides of the equation: Finally, we divide the equation by 4. Thus, y equals 5. Answer: Option C.
Each month she puts in 20......therefore annually she deposits (20 * 12) = 240 y = 240x + 200
