A negative times a negative is a positive, and a negative times a positive is equal to a negative. I’ve never used that program so if that what u need help with sorryyy
Answer:
12 sides
Step-by-step explanation:
To find the number of sides of a regular polygon with the sum of interior angles of 1800 degrees, we will follow the steps below;
first write down the formula for finding sum of the interior angle of a polygon
s= (n-2)180
where s is the sum of the interior angle and n is the number of side
from the question given, sum of the interior angle s=1800 degrees
substitute s=1800 degree into the formula and solve for n
s= (n-2)180
1800 = (n-2)180
divide both-side of the equation by 180
1800/180 = n-2
10 = n - 2
add 2 to both-side of the equation
10 + 2 = n
12 = n
n= 12
The polygon have 12 sides
Answer:

8/6=4/3
Answer:
In the year 2010
Step-by-step explanation:
we have
where
A is the population in thousands
t is the number of years since 1998
so
For A=297 thousands
substitute and solve for t
simplify
Apply ln both sides
![ln(1.485)=ln[e^{0.033t}]](https://tex.z-dn.net/?f=ln%281.485%29%3Dln%5Be%5E%7B0.033t%7D%5D)
Remember that
1998+12=2010
Answer: x= -2/5 or x= -0.4
combine like terms on left side and get -11+2x. then combine terms on right side and get -13-3x. add the 11 to the right side and get 2x= -2-3x
then add over the 3x and get 5x=-2
and finally divide the -2 from 5x and get -2/5
