Answer:

see explanation

Step-by-step explanation:

product means to multiply, hence the product of 12 and k is

12 × k = 12k ( this is 84 means equal to 84 ), that is

12k = 84 ( divide both sides by 12 )

k = 7 ← is the solution

Answer:

B) T = 2πr/v

Step-by-step explanation:

To solve the given equation for T, multiply it by T/v.

$v=\dfrac{2\pi r}{T}\\\\v\dfrac{T}{v}=\dfrac{2\pi r}{T}\cdot\dfrac{T}{v}\\\\T=\dfrac{2\pi r}{v} \qquad\text{simplify}$

$=\dfrac{1}{x+2}\cdot\dfrac{x-5}{x-5}+\dfrac{6}{x-5}\cdot\dfrac{x+2}{x+2}\\\\=\dfrac{1(x-5)+6(x+2)}{(x+2)(x-5)}\\\\=\dfrac{7x+7}{x^{2}-3x-10}$

Usually, the "simplified" form has the polynomial multiplied out (as immediately above), rather than factored. If you want it factored, you can remove a factor of 7 from the terms of the numerator to get 7(x+1)/((x+2)(x-5)).
