Write a polynomial function of minimum degree with real coefficients whose zeros include those listed. Write the polynomial in standard form.

3, -13, and 5 + 4i

A. f(x) = x4 - 8x3 - 12x2 + 400x - 1599
B. f(x) = x4 - 200x2 + 800x - 1599
C. f(x) = x4 - 98x2 + 800x - 1599
D. f(x) = x4 - 8x3 + 12x2 - 400x + 1599

What is the next step in the given proof? choose the most logical approach. a. statement: m 1 + m 2 + 2(m 3) = 180° reason: angle addition b. statement: m 1 + m 3 = m 2 + m 3 reason: transitive property of equality c. statement: m 1 = m 2 reason: subtraction property of equality d. statement: m 1 + m 2 = m 2 + m 3 reason: substitution property of equality e. statement: 2(m 1) = m 2 + m 3 reason: substitution property of equality
