can some one please help me with this test
1.
Choose the correct solution in roster form.

N is the set of real numbers that are factors of 20. (1 point){2, 4, 5, 10}
{2, 4, 6, 8, 10, 12, 14, 16, 18, 20}
{1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20}
{1, 2, 4, 5, 10, 20}

2.
Suppose U = {1, 2, 3, 4, 5, 6, 7, 8} is the universal set, and P = {1, 3, 5, 7}. What is P'? (1 point){2, 4, 6, 8}
{1, 2, 3, 4, 5, 6, 7, 8}
{1, 3, 5, 7}
{1, 3, 5, 7, 8}

3.

Solve.

3x + 10 ≥ 4
(1 point)x ≥ –2
x ≤ 2
x ≤ –2
x ≥ 2
