32.
Step-by-step explanation:
I accidentally put my age too high. Im only in middle school but 32 could be one answer. If two sides are the same then it could be an isoceles triangle or whatever.
13. Is 18
15. Is 86
17 is 5
19 is 15
21 is 24
23 is 29
2x + 4 = 3(x - 2) + 1
2x + 4 = 3x - 6 + 1
2x + 4 = 3x - 5
9 = x
So x = 9
