81k^2 - m^2 factors to
(9k + m)(9k - m)
Prove this by FOILing.
First - 81k^2
Outer - (-9km)
Inner - 9km
Last - (-m^2)
Put it into equation form
81k^2 - 9km + 9km - m^2
And combine terms to get the original equation,
81k^2 - m^2.

Since all straight lines have an angle of 180 degrees if the exterior angle is equal to 113 degrees than you just subtract 113 from 180 which will equal 67.
Answer:
48 miles
Step-by-step explanation:

The remaining values will be<u> 19, 20, 21, 22 and 23</u>
<h3 /><h3>System of equations</h3>
Given the following parameters
Ethan's score = x points
His younger sister's score = 8 points
If their total score is y points, hence the equation relating x and y is expressed as:
x + 8 = y
x = 8 - y
If x = 10
y = x + 8
y = 18
The ramining values will be<u> 19, 20, 21, 22 and 23</u>
