if m is divisible by 3, m = 3n for some integer n. then 3n = 121 - 5k n = 40 1/3 - 5/3 k 40 1/3 - 5/3 (0) = 40 1/3 40 1/3 - 5/3 (1) = 38 2/3 40 1/3 - 5/3 (2) = 37 and 40 1/3 - 5/3 (5) = 32 when k = 2 mod 3, m = 0 mod 3, but m can be eit…

rational root theorem suggests trying ±1, ±2, and so on (factors of 12) as roots. synthetic division with x = 1 gives us (x - 1)(x² + x - 12) = (x - 1)(x + 4)(x - 3)

that's x+4 and 5x+2? your plus signs don't show. (x+4) / (x-2) = r = (5x+2)/(x+4) (x+4)² = (x-2)(5x+2) x² + 8x + 16 = 5x² - 8x - 4 0 = 4x² - 16x - 20 x² - 4x - 5 = 0 (x - 5)(x + 1) = 0 x = 5 or x = -1 so r = (5+4)/(5-2) = 3 = (25+2)/(5+4)…

If the interest rate is 5%, you multiply by 1.05 to do the compounding (think about it). The 1 is all of the amount and the .05 is the interest on the amount, so when you add the interest to the original, you get (1 + interest rate) TIMES the origi…
