17
If your birthday has already passed for this current year, then the answer is x - 17, where x is the current year. Otherwise, it will be x - 16.
225 = 15 x 15 256 = 16 x 16 289 = 17 x 17
1 x 16 = 16 2 x 16 = 32 3 x 16 = 48 4 x 16 = 64 5 x 16 = 80 6 x 16 = 96 7 x 16 = 112 8 x 16 = 128 9 x 16 = 144 10 x 16 = 160 11 x 16 = 176 12 x 16 = 192 13 x 16 = 208 14 x 16 = 224 15 x 16 = 240 16 x 16 = 256 17 x 16 = 272 18 x 16 = 288 19 x 16 = 304 20 x 16 = 320
220 8 x 2 = 16 and 17 x 6 x 2 = 204 and 16 + 204 = 220
x-17 = 16-5 x = 16-5+17 x = 28
16*17=272
17x = 17 + x Subtract x from both sides. 16x = 17 Divide each side by 16. x = 17/16 or 1 and 1/16 or 1.0625 Check it. 17 x 1.0625 = 18.0625 17 + 1.0625 = 18.0625 It checks.

17 x 16 = 272
5/16 + x = 8/17x = 8/17 - 5/16x = (8/17 x 16/16) - (5/16 x 17/17)x = 128/272 - 85/272x = (128 - 85) / 272x = 43/272
17 feet x 16 feet = 272 square feet
272 (16 x 17)
-1
14 + 16 + 17 + 18 - 42 x 79 + 586.3 x 86.26= 24
