• ### If 38.4023 = [1 - 1/(1 + r)^48] / r, how can I solve for r?

This is from the formula for the PV of an Annuity. PV is 16,200, N is 48, and PMT is 421.85. So the "factor" must be 16,200 / 421.85, or 38.4023. So 38.4023 = [1 - 1/(1 + r)^48] / r. How can I solve for R? I'm stumped.

• ### Why do so many formulas in Geometry require Squaring?

Examples: E=MC Squared; the famous PiR Squared; A Squared + B Squared = C Squared. There must be some logic to squaring everything, but I don't get it.

• ### Can I retrieve Deleted messages in Outlook Express?

When I close Outlook Express, a message always pops up saying "To free up disk space, OE can compact messages for me." I did that once, and it emptied my Deleted and Sent folders. Can I still retrieve them? And how can I block that message from coming up all the time? Thanks
