Prime, because the only number that can go into it are 19 and 1
Answer: (x + 3, y - 4)
Explanation: The shape in the middle goes to the right three and down four to match the shape at the bottom
As x = 5 & z=12,
<span>2/3 = y /(xz) = y/(5*12) </span>
<span>= y/60 </span>
<span>so y / 60 = 2/3 </span>
<span>y = (2*60)/3 </span>
<span>= 40</span>
