Answer:
9841
Step-by-step explanation:
Each time the number of shaded triangles is multiplied by 3. So this is a geometric series:
an = 1 (3)ⁿ⁻¹
The sum of the first n terms of a geometric series is:
S = a₁ (1 - rⁿ) / (1 - r)
Here, a₁ = 1, r = 3, and n = 9.
S = 1 (1 - 3⁹) / (1 - 3)
S = 9841

b^2= - 36
b^2= - 1.6^2
b^2= i^2.(+,-6)^2
b=6i
b= - 6i
or b isn't real number there is no solution....
After having a discount of 10%, we have to pay the net price: 220x90%= 198
But you have to pay 10.5% service charge, that means the service charge is 198x10.5%= 20.79
And finally you have to pay: 198+20.79= 218.79
Hope it is helpful
