Explain why the polynomial 144x^2 − 200x + 81 is not a perfect square. a. 81x ≠ 2(20x ∙ 9) b. 144x ≠ 2(20x ∙ 12) c. 200x ≠ 2(9x ∙ 12) d. 200x ≠ 2(12x ∙ 9)

Asequence has its first term equal to 4, and each term of the sequence is obtained by adding 2 to the previous term. if f(n) represents the nth term of the sequence, which of the following recursive functions best defines this sequence? (1 point) f(1) = 2 and f(n) = f(n − 1) + 4; n > 1 f(1) = 4 and f(n) = f(n − 1) + 2n; n > 1 f(1) = 2 and f(n) = f(n − 1) + 4n; n > 1 f(1) = 4 and f(n) = f(n − 1) + 2; n > 1 i will award !
