Is the statement true or false? if false, give a counterexample. for all real numbers a, b and c, a(b+c)= ab+bc

This is so hard and it’s for a test

When using the linear combination metho e linear combination method to solve a system of linear equations, the four options are:

Given: lines a and b are parallel and line c is a transversal. prove: 2 is supplementary to 8 what is the missing reason in the proof? statement reason 1. a || b, is a transv 1. given 2. ∠6 ≅ ∠2 2. ? 3. m∠6 = m∠2 3. def. of congruent 4. ∠6 is supp. to ∠8 4. def. of linear pair 5. ∠2 is supp. to ∠8 5. congruent supplements theorem corresponding angles theorem alternate interior angles theorem vertical angles theorem alternate exterior angles theorem
