I need 14 and 15 please!

14. (n-5)*4+7
15. No, this would not be neccesary because if I were to distribute 1/2 to both 4 and 6, I know that I would get half of those numbers which would give me 2x+3. I also know that if I distribute 1/3 to both 9 and 24, I would get 1/3 of each number which would be 3 and 8.

Answer:

$\frac{ {n}^{2} }{2}$

Step-by-step explanation:

$\frac{3 {n}^{5} }{6 {n}^{3} } = \frac{3}{6} \times \frac{ {n}^{5} }{ {n}^{3} } = \frac{1}{2} \times {n}^{5 - 3} = \frac{1}{2} \times {n}^{2} = \frac{ {n}^{2} }{2}$

DOES ANYONE USE THIS APP? <br>I NEED HELP

Answer:

You can determine the root of the equation by multiple methods. However, that answer is correct. The root is -2.

Step-by-step explanation:

A root is where the graph crosses the x-axis. One trick I use to see if it is a root is by taking the numerator and plugging in the number for x. For example, $\frac{x+2}{x^{2} -2}$ , and take the -2 and plug it in for x. The numerator would cancel out because -2 + 2 = 0. That is the way you can determine if it is a root or not.
