How to simplify boolean algebra and check for equivalent equations?

Boolean Algebra 13. Select the Boolean expressions that share the same truth table as A-B-C+A-B-C+A-B-C+A-B-C Select all that apply. O A. B.C+A-B-T+A-B-C+A-B-C O B. (A+B+C).(A+B+C)-(A+B+C) A+B+C) O C. (A+B+C). (A+B+C)-(A+B+C). (A+B+C) O D . (A+B+C) A+B+C).(A+B+C) (A+B+C) O E. (1+B+C)(A+B+C). (A+B+C)-(A+B+C) 14. Select all equivalent Boolean equations. O A. B+AC OB. AB+AC + BC + BC O c. (+B)A+C)(B+C)(B+C) OD. AB+AC+C 15. Select the Boolean expression(s) matching the filled areas of this Venn diagram. Big Red Square O A. (Big +Red) + Square. (Big - Red) O B. (Big - Red). (Square+Big+Red) O C. Square. (Big + Red) + Big. Red OD. Square. (Big +Red) + Big-Red) 16. Select all Boolean expressions that are equivalent to: PQ+RS O A. P+Q+R+S OB. P+Q+R+S O c. PQ-RS OD. PORS
