No I hope this helps you!
The answer is going to be 3y^1/ because 15 divide by 5 is a 3 and 9 plus 3 is 12 so 1/ is going to be the exponent and the answer will be 3y^12
From my research on the internet, the image attached supports this problem. The two lines are parallel, as supported by the converse of corresponding angles postulate. It states that:<span> If a </span>transversal<span> intersects two lines and the corresponding angles are </span>congruent<span>, then the lines are parallel.</span>
