Discrete math question. Can not figure out which one is wrong.

Let the universe of discourse contain all integers. Determine if the following statements are true: 3n(n^2 Greaterthanorequalto 6n) A. No, n = 2 does not satisfy the statement. B. Yes, n = 7 satisfies the statement. C. No, no values of n satisfy the statement. D. Yes, all values of n satisfy the statement. 3d(d^2 -4 = (d - 2)(d + 2)) A. No, no values of d satisfy the statement. B. Yes, d = 1/2 satisfies the statement. C. No, d = 2 does not satisfy the statement. D. Yes, d = 1 satisfies the statement. d(d^2 + 4d + 4 = 0) A. Yes, d = 2 satisfies the statement. B. Yes, all values of d satisfy the statement. C. No, no values of d satisfy the statement. D. No, d = 1 does not satisfy the statement. 3d(d^2 - 4d + 4 = 0) A. Yes, d = 2 satisfies the statement. B. Yes, all values of d satisfy the statement. C. No, only some values of d satisfy the statement. D. No, no values of d satisfy the statement. n(n^2 Greaterthanorequalto 6n) A. No, n = 2 does not satisfy the statement. B. Yes, all values of n satisfy the statement. C. Yes, n = 2 satisfies the statement. D. No, no values of n satisfy the statement. n(n^2 lessthanorequalto n) A. Yes, n = 2 satisfies the statement. B. No, no values of n satisfy the statement. C. Yes, all values of n satisfy the statement. D. No, n = 2 does not satisfy the statement.

Explanation / Answer

3.c) False,because when d=-2 satisfy the statement.

5.d)False,because when n=7 satisfy the statement..

6.b)False.because when when n=0,1 satisfy the statement...
