B. complex numbers.

<h2>Step-by-step explanation:</h2>

We know that a complex number is always written in the form of :

a+ib

where a and b are real numbers and i is the square root of -1.

i is called an imaginary number.

If a>0 and b>0 then the point lie in the first quadrant.

if a>0 and b<0 then the point lie in the fourth quadrant.

Driving to your friend's house, you travel at an average rate of 35 miles per hour. On your way home, you travel at an average r

kenny6666 [7]

Answer:

14 miles

Explanation:

The relation that will be used to solve this problem is:

$Distance = Velocity*Time$

which can be rewritten as:

$Time = \frac{Distance}{Velocity}$

Assume that:

Distance from your house to your friend's house is d

Time taken from your house to your friend's house is t₁

Time taken from your friends house to your house is t₂

1- From your house to your friend's house:

Average rate = 35 miles/hour

Therefore:

$t_{1} = \frac{d}{35}$

2- From your friend's house to your house:

Average rate = 40 miles per hour

Therefore:

$t_{2} = \frac{d}{40}$

3- Round trip:

We know that the round trip took 45 minutes which is equivalent to 0.75 hours

This means that:

t₁ + t₂ = 0.75 hours

$\frac{d}{35}+\frac{d}{40}=0.75\\ \\\frac{40d + 35d}{1400}=0.75\\ \\\frac{75d}{1400}=0.75\\ \\ 1050 = 75d\\ d=14 miles$

Hope this helps :)
