Ganezh [65]

Answer:

<em>276 guests were at the wedding. </em>

Step-by-step explanation:

\frac{1}{3} + \frac{5}{12} = \frac{4+5}{12} = \frac{9}{12}

1 - \frac{9}{12} = \frac{3}{12} = \frac{1}{4}

\frac{1}{4} of the guests are 69 guests ⇒ 69 × 4 = <em>276 guests were at the wedding.</em>

Simplify 13 over the quantity of negative 3 plus 2i.
jasenka [17]

\frac{13}{(-3+2i)}

To simplify we need to rationalize it. which can be done by multiplying composite of denominator. That is multiply by -3-2i

=\frac{13}{(-3+2i)}*\frac{(-3-2i)}{(-3-2i)}

Now multiply numerator with numerator and denominator with denominator

=\frac{(-39-26i)}{(-3)^2-(-2i)^2}

=\frac{(-39-26i)}{9-(4i^2)}

=\frac{(-39-26i)}{9-(4(-1))}

=\frac{(-39-26i)}{9-(-4)}

=\frac{(-39-26i)}{9+4}

=\frac{(-39-26i)}{13}

=-3-2i

Hence final answer is =-3-2i
