Question

пожалуйста помогите ​

Answer 1

$\displaystyle\bf\\\frac{c^{2}+4c+4}{c^{2} -4} =\frac{(c+2)^{2} }{(c+2)\cdot(c-2)}=\frac{c+2}{c-2} \\\\\\c=5\\\\\\\frac{c+2}{c-2}=\frac{5+2}{5-2} =\frac{7}{3} =2\frac{1}{3}$

Answer 2

Ответ:      2 1/3.

Объяснение:

(c²+4c+4)/(c²-4) = (c+2)²/(c+2)(c-2) = (c+2)/(c-2);

при с=5 =>

(c+2)/(c-2) = (5+2)/(5-2) = 7/3 = 2 1/3.
