the answer is 22464, because if they marched 1872 yard for the first side, you can multiply it by 3 because there are 3 feet in one yard. Then you multiply that by 4 because there are 4 sides in a square
Slope (y2-y1)/(x2-x1)
(10-0)/(10-8) = 10/2 = 5
The slope is 5
So you question is most likely about a triangle DEF with the 3 angles being named D, E, F. The triangle would look something like the image attached below.
If that is what is being asked then i need more info to answer but
By Definition it would be 180 degrees.

To find slope of two points we will need to use this equation: 
( 6 , -12 ) ( 15 , -3 )
Now let's replace the equation with the numbers. (it will be a fraction).
= 
The equation equals 9 over 9, which also equals 1.
The slope of the line is 1.
Answer:
For question 6 there are 3 steps, and for question 7 there are 2 steps
Step-by-step explanation:
Question 6:
step 1. 89 x 2=178
step 2. 89 x 3=267
step 3. 267 + 178=445
Question 7:
step 1. 35 x 3= 105
step 2. 25 x 5= 12
Your're welcome :)
