Good afternoon, I need the following 6 proofs done with full explanations and complete sentences. Please do not bid if you can not write in native, fluent English (so absolutely no broken English). I want A+ correct answers for each. Absolutely no plagiarizing from the Internet or solution manuals. This is due Sunday – Oct 26 – 9:00 PM, EST.
