Answer:
i don't think so that's why it's for quadratic and not others like linear or geometric, I might be wrong thiugh
Answer:
225
Step-by-step explanation:
Using the basic components of summation ∑
∑n =
n(n + 1) and ∑1 = n
Thus
∑ (2n - 1) ← for n = 1 to 15
= ∑2n - ∑1
= 2∑n - ∑1
= 2 (
n(n + 1)) - n
= n(n + 1) - n ← Evaluate for n = 15 ( the upper value )
= 15 × 16 - 15
= 240 - 15
= 225
You can break the shape up into a rectangle and a right triangle.
Use your trig ratios to find the missing sides.
Add all the sides up and you have your perimeter!

<em>*notice how one of the 10 is left out because it is inside the shape so we can't use that to find perimeter.</em>

C never, there are always different methods to solve a problem but don't forget that the equation always stays the same!
