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
Answer:
(0, 207)
Step-by-step explanation:
We calculate y-intercept by substituting 0 for x.
The equation becomes:
3*62-6*(0)+21=207
y intercept is (0, 207)
Given that the number is x,
10% increase will give us a new number of:
110/100*x
=1.1x
10% decrease will give us a new number of:
90/100*1.1x
=0.99x
This implies the new number is less than the original number
