That would be the same as the sum of the interior angles of the regular pentagon which is 540 degrees.

pantera1 [17]

He now has 44 so subtract 17 from that and you get 27 (1/2 of the number of his original stamp collection). Then add 27 +27 and you get 54. I believe 54 is the answer. Hope that helps!

When is the equation <img src="https://tex.z-dn.net/?f=%5Cfrac%7Bx-7%7D%7Bx%5E2-4x-21%7D%20%3D%5Cfrac%7B1%7D%7Bx%2B3%7D" id="Tex

Notice that

$x^2 - 4x - 21 = (x - 7) (x + 3)$

so on the left side, a factor of <em>x</em> - 7 in the numerator and denominator can cancel

$\dfrac{x-7}{x^2-4x-21} = \dfrac{x-7}{(x-7)(x+3)} = \dfrac1{x+3}$

But we can only cancel them out as long as <em>x</em> ≠ 7 (because otherwise we'd have the indeterminate form 0/0 on the left side).

So, the equation is true for all <em>x</em> <u>except</u> <em>x</em> = 7. In set notation,

$\{x \in \mathbb R \mid x \neq 7\}$

In interval notation,

$(-\infty,7)\cup(7,\infty)$
