Area of hexagon = 3√3 / 2 (18^2) = 842
area of rectangle = 18 * 21 = 378
area of shaded = 842 - 378 = 464
answer
A. 464 square units
Answer: aₙ = 3 + 4ⁿ⁻¹
So the formula would be:
<u>aₙ = 3 + 4ⁿ⁻¹</u>
Where a₁ = 3
Common Ratio (r) = 4
And n = the term number that needs to be found out
Step-by-step explanation:
<u>Let's check if the answer is right:</u>
To find the 1st number in the term we can substitute 1 in for n in the equation:
a₁ = 3 + 4¹⁻¹
a₁ = 3 + 4⁰
a₁ = 3 + 1
a₁ = 4
And if going back and checking the first number in the sequence given is indeed 4, therefore this equation is correct
Hope this helps!
I am sure it is (1,4) hope this helps
Since there are 2 digits in 54, the very last digit is the "100th" decimal place. So we can just say that . 54 is the same as 54/100. terms by dividing both the numerator and denominator by 2.
