Help evaluating the limits of these two problems, one of which is a complex fraction

I like finding limits, but complex fractions and I do not get along. I would greatly appreciate it if someone could help me evaluate the limits of the following two problems (step-by-step). For #37, I received a different answer from Mathway.com, which was also a different answer from the back of my book, so I am very lost. I appreciate the help!

Thank you so much!! I can't believe I over-thought it that much. I was trying to multiply the numerator by 4+x and not multiply the denominator by anything...hence my headache-on-top-of-headache... Thanks!! :-)
