URGENT PLEASE HELP In this unit, you learned about rational and irrational numbers. The following is a number and two students’ explanations on whether the number is rational or irrational.

Start-fraction Start Root 2 End Root over 8 end-fraction

Student A: Start-fraction Start Root 2 End Root over 8 end-fraction is a rational number because it can be written as a fraction.

Student B: Start-fraction Start Root 2 End Root over 8 end-fraction is an irrational number because start root 2 end root is irrational.

Evaluate the reasoning provided by both student A and B, and correct the errors. Make sure to provide proper reasoning.
Come up with one challenging rational or irrational number in your post. Make sure to not include the answer.

Given: ad¯¯¯¯¯ is an altitude. prove: ab2+ac2=cb2 right triangle a b c with right angle a. point d lies on side b c and segment a d is drawn. angle a d c is a right angle. drag and drop a reason into each box to correctly complete the two-column proof. statement reason ad¯¯¯¯¯ is an altitude, and ∠bac is a right angle. given ∠adb and ∠adc are right angles. definition of altitude ∠bac≅∠bda ? ∠bac≅∠adc ? ∠b≅∠b ? ∠c≅∠c reflexive property of congruence △abc∼△dba ? △abc∼△dac aa similarity postulate abbd=cbab ? ab2=(cb)(bd) cross multiply and simplify. acdc=cbac polygon similarity postulate ac2=(cb)(dc) cross multiply and simplify. ab2+ac2=ab2+(cb)(dc) addition property of equality ab2+ac2=(cb)(bd)+(cb)(dc) substitution property of equality ab2+ac2=(cb)(bd+dc) ? bd+dc=cb segment addition postulate ab2+ac2=cb2 substitution property of equality
