Learning Target L5: I can correctly structure a careful mathematical proof including all relevant English and mathematical statements. Please remember the academic integrity policy that you swore to uphold. Proofs can be challenging. Just try your best. If you don't get it this week, you have many more opportunities! Advice: If you still have an N in this learning target and you're having trouble, send me an email/message with what you have, and I'll try to help push you in the right direction (without giving it all away). want to help you succeed. Seriously. 1. Prove that if a and b are integers and a² +6² is even, then a +b is even. [Big Hint: try a contrapositive proof. Square it. See what happens.] 2. Prove that if 5 | n, then 3n - 45 is divisible by 15. You can use our text, videos, notes etc, posted to Teams and Blackboard. No other outside resources (including humans) are allowed.

The Solution to the answer is not complete Please clarify
Is it okay for you to write a detailed solution for this?
Please solve the last 3 problems, I just submitted and have solution to the first 3 problems .
As I was driving along the highway to Cleveland, I noticed a speedometer check along the side of the road with posted signs 1 mile apart. I timed us and found that it took us 5 minutes and 45 seconds to travel 5 miles. We had the car set on cruise control, so we were traveling at a constant speed. A while later we passed a sign that said “Akron 76 miles.” At that speed, how long did it take us to drive those 76 miles to Akron? (Convert your decimal answer to an equivalent number of hours, minutes, and seconds. For example, 7.104 hours = 7 hours 6 minutes 14 seconds.)
Can you please further explain how you found the solution.
