Hello!
To find the area of a hexagon you do 3

where a is one of the sides
Since the perimeter is 60 we can do 60/ the sides of the shape
60/6 = 10
So one side is equal to 10
you put that into the formula to get the area of a hexagon and you get 259.81
Hope this helps!
Commutative because your switching the order

Find the nth term
tn = (-1 )^(n -1) * (a)^n answer or
tn = (-1)^(n - 1) * 2^n
where a is defined as the first term (it usually is given that designation).
Try a few to make sure the formula is correct
<em>n = 1</em>
t1 = (-1)^(1 - 1) * 2^1
t1 = (-1)^0 * 2
t1 = 1 * 2 = 2
<em>n =2</em>
t2 = (-1)^(2 - 1) * 2^2 = (-1)^1 * 4 = -4
Answer:
graph c
Step-by-step explanation:
because it is a more perfect line through the dots then the others, thats how you can always tell
The idea being, we first, move the repeating part to the left of the decimal point, by simply multiplying it by a power of 10, in this case, we need to move 318, so we need then 1000, 3 decimals, 3 zeros.
and we'll make the expression a variable, so let's do so first,
