Way too much work for two points!
For the first question:
19.(37 * 83) + (37 * 17) = 37 * (83+17) = 3700
This is the distributive property done backwards.

If you had asked 1 or 2 questions, we'd be falling all over ourselves answering them, hoping for the best answer points, but even the most generous of us is not interested in doing your homework for you.

i can answer them but there's to many, if only u had more like 3 questions.

yes, I can. I believe you could do if you looked at them.
