Which of the following is closest to the distance, in miles, across the lake from point A to point C?

Use the x-intercept method to find all real solutions of the equation.x^3-10x^2+27x-18=0

How do you write something in scientific notation?

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
