Question

Simplify each expression.

Answer 1

Answer:

3) 7$\frac{7}{5(n+2)}$

5) $\frac{9}{k+2}$

7) $\frac{7b}{b-9}$

Step-by-step explanation:

3) $\frac{7n+5*7}{5n^{2}+(5*7)n+2*5^{2} }$

$\frac{7(\frac{7n}{7}+\frac{5*7}{7} ) }{5(\frac{5n^{2} }{5}+\frac{5*7n}{5}+\frac{2*5^{2} }{5} )}$

5) $\frac{3^{2}(k+5) }{k+2} * \frac{1}{k+5}$

7)$\frac{5*7*b^{2}+7^{2*b} }{(2*5)b+2*7}$ / $\frac{b-9}{2}$

$\frac{7b (\frac{5*7b^{2} }{7b} + \frac{7^{2}*b }{7b} )}{2(\frac{2*5b}{2}+\frac{2*7}{2}) }$ / $\frac{b-9}{2}$

This is my first time using the equation function, hopefully I did it correct.
