Answer:

Please check the explanation.

Step-by-step explanation:

Considering the expression

$9i+2\left(7+3i\right)$

Applying the distributive law

$a\left(b+c\right)=ab+ac$

so the expression becomes

$=9i+2\cdot \:\:\:7+2\cdot \:\:\:3i$

Group like terms

$=9i+14+6i$

Add similar elements: 9i+6i=15i

$=15i+14$

Answer: 336.80 miles, $15.85^{\circ}$ North of east

Step-by-step explanation:

Given

Plane lands at a point 324 miles east and 92 miles north

Distance is given by using Pythagoras theorem

$\Rightarrow d=\sqrt{324^2+92^2}\\\\\Rightarrow d=\sqrt{113,440}\\\\\Rightarrow d=336.80\ \text{miles}$

Direction is given by using figure i.e.

$\Rightarrow \tan \theta=\dfrac{92}{324}\\\\\Rightarrow \tan \theta=0.2839\\\\\Rightarrow \theta=15.85^{\circ}$

Direction is $15.85^{\circ}$ North of east
