Answer:
C) -0.828
Step-by-step explanation:
(I used a regression calculator)
We know that
Area of a regular polygon = (1/2)*apothem<span>*perimeter
</span>perimeter <span>of the regular decagon=10*a
where
a is the length side of the decagon
in this problem
a=1.8 ft
so
</span>perimeter of the regular decagon=10*1.8----> 18 ft
Area of a regular decagon = (1/2)*2.8*18----> 25.2 ft²
<span>Round to the nearest whole number------> 25 ft</span>²
the answer is
25 ft²
Answer:
326.85 inches squared
Step-by-step explanation:
A=πr^2
Pi * 10.2 ^2
All in all, we are selecting from a pool of 17 members (4+9+4 = 17). So seeing we have 4 democrats, the probability would be 4/17.
Normally we would simplify the fraction from there but 4/17 is already the simplified form. Therefore that is already the answer.
Answer:
7x^2+21x+14
Step-by-step explanation:
With this all we have to do is foil:
first outside inside last
first: 7x^2
outside: 14x
inside: 7x
last: 14
we now combine them to
7x^2+14x+7x+14
we add like terms
7x^2+21x+14
