Answer:
(n-2)×180=1080
180n -360=1080
180n = 1080+360
180n =1440
dividing by 180
n=8
hence it is a regular polygon with 8 sides .I.e it is an octagon
Step-by-step explanation:
we are given the total interior angles in the polygon and we know that the formula to find the total interior angles of a polygon is (n-2) ×180
where n is the number of sides
Answer:
8n^2+7n+2/3
Step-by-step explanation:
combine like terms
5n+2n=7n
Answer:
The number of skateboard company sell during the month of August = 55
Step-by-step explanation:
We have given,
Profit function for Bob, P = x²+ 10x - 12
Bob's profit during August month is $3,563
That means, P = $3,563
We can use the profit formula given for Bob's profit:
P = x² + 10x - 12
Plug P =$3,563 in above formula.
i.e 3,563 = x² + 10x - 12
or 0 = x² + 10x -12 - 3,563
or 0 = x² + 10x - 3575
or x = 55, -65
Since number of skate boards can not be negative.
So we consider x= 55
Hence the number of skateboard company sell during the month of August = 55.
