Select the work that correctly represents 3/5 + 4/7 PLEASE HELP ASAP!

1. = (3x5/5x5) + (4x7/7x7)
= 15/25 + 28/49
= 43/74

2. (3+4/5+7)
= 7/12

3. (3x7/5x7) + (4x5/7x5)
= 21/35 + 20/35
= 41/35

Match the following reasons with the statements given to create the proof. 1. do = ob, ao = oc sas 2. doc = aob given 3. triangle cod congruent to triangle aob vertical angles are equal. 4. 1 = 2, ab = dc if two sides = and ||, then a parallelogram. 5. ab||dc if alternate interior angles =, then lines parallel. 6. abcd is a parallelogram cpcte
