Which statement is true about the difference 2 square root of 7 − square root of 26? it is rational and equal to −2. it is rational and equal to 0. it is irrational and equal to −2 square root of 7. it is irrational and equal to square root of 7.

Consider the proof. given: segment ab is parallel to line de. prove: what is the missing statement in step 5?

Solve each quadratic equation by factoring and using the zero product property. x^2 + 18x = 9x

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
