To evaluate 15m for m equals 7, you simply substitute 7 in place of m in the expression. So, 15m becomes 15 * 7. Multiplying 15 by 7 gives you the result of 105. Therefore, 15m, when m equals 7, is equal to 105.
If it were, then 17 squared would equal 8 squared plus 15 squared. ie 289 would equal 64 + 225 which it does, so it is a pythagorean triangle.
16-n equals 8 = 8
16. Because if y=8 then the question becomes 8+8. Which equals 16.
