Answer:
Width is 14 ft, length is 28 ft
Step-by-step explanation:
We know that the length is twice as long as the width. This can be represented by L=2W.
The equation to solve this is 84=W+W+L+L. We can replace both the L variables with 2W, since that is what L equals.
84=W+W+2W+2W. We simplifiy to get 84=6W. We divide 84 by 6 and get W=14.
Now that we know the width, finding the length is easier. L=2(14). L=28 ft.
To check our math we can do 28+28+14+14. 56+28=84 ft.
Therefore, the width is 14 ft and the length is 28 ft.

Step-by-step explanation:
d) Aislinn's average per month on her car is 1,751 miles per month.
<h3>How to find the average speed?</h3>
The average speed is calculated by dividing the total distance traveled by the total time it took to travel that distance. Speed is the rate at which something moves at any given time.
Average speed is the average rate of speed over the course of a journey. Velocity exists as the directional speed of a moving object as an indication of its rate of change in position as observed from a specific frame of reference and measured by a specific time standard.
Given,
After 8 months, the odometer read 14,010 miles.
Solution:
t = 8,
d = 14,010 miles,
s = ?
s = d/t
s = 14,010/8
s = 1751 miles/month.
Aislinn drove an average of 1,751 miles per month.

Answer:
3(cos(75°) +i·sin(75°)) and 3(cos(255°) +i·sin(255°))
Step-by-step explanation:
Using Euler's formula, this can be written as ...
x^2 = 9·e^(i5π/6)
Then the square roots are ...
x = (±√9)e^((i5π/6)/2) = ±3e^(i5π/12)
Of course, multiplying by -1 is the same as adding 180° to the angle.
The square roots are ...
3(cos(75°) +i·sin(75°)) and 3(cos(255°) +i·sin(255°))
