Answer:
A ≈ 269.81 cm²
Step-by-step explanation:
This shape is a hexagon (it has 6 sides) so let's use the formula for the area of a hexagon.
A = 
Where s is the length of the sides
Substitute:
A = 
A = 
Solve:
A = 
A = 
Multiply the numerator:
A = 
A ≈ 
(The numerator reflects a rounded number, but the actual calculations are exact)
Divide the fraction:
A ≈ 
A ≈ 2.6(100)
Multiply:
A ≈ 2.6(100)
A ≈ 269.81 cm²
Therefore, the area is approximately 269.82 cubic centimeters.
The answer is 4,000 ft squared because since the sides are 100 ft and 80ft then we need to multiply them which is 8,000 then divide that by 2 since it’s a triangle which is 4,000 ft squared.
No because they 90 to 200 is 110 but 200 to 325 is 125
110 obviously does not equal 125
Step-by-step explanation:
a).
n! is

(n-3)! is

If we divide the two, everything behind (n-3) will just cancel out so we would be left with only

So the answer to a is

b
Permutations formula of P(6,4) is
6!/(6-4)!, or 6!/2!.

Then we divide by 4!

The answer to b is 15
