Answer:
A = {11, 12, 13, 14, 15, ....}
B = {-4, -3, -2, -1, 0, 1, 2, 3, 4}
C = {}
D = {}
Step-by-step explanation:
A is just natural numbers greater than 10 so it's 11, 12, and so on.
B is an integer between -4 and 4 inclusively. |m| ≤ 4 is same as -4 ≤ m ≤ 4
C and D is quadratic equation with no real solution, and since the set must be in real numbers, C and D are both empty set.
