If f(x) = 3x + 10x and g(x) = 5x - 3, find (f - g)(x). A. 3X + 5x + 3
B. 3x - 5x+3
C. 3X + 15x - 3
O D. 18x - 3

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
