-10n + 24 + 30n = -36<br> Solve this equation

vladimir1956 [14]

Step-by-step explanation:

$- 10n + 24 + 30n = - 36$

Collect like terms and simplify

[tex] -10n+30n=-36-24 \\ 20n = -60 [/tex]

Divide both sides of the equation by 20

[tex] 20n/20 = -60/20 \\ n=-3 [/tex]

<h3>Answer: Choice D) </h3>

Work Shown:

$(f+g)(x) = f(x)+g(x)\\\\(f+g)(x) = \frac{x-23}{x^2+9x-36}+\frac{1}{x+12}\\\\(f+g)(x) = \frac{x-23}{(x+12)(x-3)}+\frac{1(x-3)}{(x+12)(x-3)}\\\\(f+g)(x) = \frac{x-23+1(x-3)}{(x+12)(x-3)}\\\\(f+g)(x) = \frac{x-23+x-3}{x^2+9x-36}\\\\(f+g)(x) = \frac{2x-26}{x^2+9x-36}\\\\$

We must require that $x \ne -12$ and $x \ne 3$ to avoid having 0 in the denominator. This is why choice D is the answer.
