Sherlyn · Answer 1

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.
