Answer:

Step-by-step explanation:

If MN is tangent of a circle then the angle M is a right angle.

We have a dimeter of acircle d = 8 cm.

Therefore the radius CM = 8 cm : 2 = 4cm.

In a right triangle CMN use the Pythagorean theorem:

$CM^2+MN^2=CN^2$

Substitute CM = 4cm and CN = 9.9 cm:

$4^2+MN^2=9.9^2$

$16+MN^2=98.01$ <em>subtract 16 from both sides</em>

$MN^2=82.01\to MN=\sqrt{82.1}\\\\MN\approx9.1$

Answer:

$\frac{p^2-25}{p^2-10p+25}$

We can factorise the numerator with the difference of squares formula: $x^2-y^2=(x+y)(x-y)$

-----------------------------

$\frac{p^2-5^2}{p^2-10p+25} =\frac{(p+5)(p-5)}{p^2-10p+25}$

Now we can factorise the denominator:

$\frac{(p+5)(p-5)}{p^2-10p+25} =\frac{(p+5)(p-5)}{(p-5)^2}$

$\frac{(p+5)(p-5)}{(p-5)^2} =\frac{(p+5)(p-5)}{(p-5)(p-5)}$

Cancel out the common factor of (p-5):

$\frac{(p+5)(p-5)}{(p-5)(p-5)} =\frac{(p+5)}{(p-5)}$
