1. The tables represent a ratio of 3:5. For example, 6 x 3 = 18, and 6 x 5 = 30. Also, 20 x 3 = 60, and 20 x 5 = 100.
2. The table has a ratio of 3:4, so the missing blank is 64.
If you’re looking for the answer it’ll be 0
30-40= -10
-10+10= 0
Is not factorable over real numbers, but if you want to use imaginary numbers then it would be (x+13i) (x-13i)
Answer with rational numbers: Not Factorable
Answer with imaginary numbers: (x-13i)(x+13i)
