Answer:
Step 3 they took the square root incorrectly
Step-by-step explanation:
5 ( x-2)^2 +6 = 86
Subtract 6 from each side
5 ( x-2)^2 +6 -6= 86-6
5 ( x-2)^2 = 80
Divide each side by 5
5 ( x-2)^2 /5 = 80/5
(x-2)^2 = 16
Take the square root of each side
sqrt((x-2)^2) = ±sqrt(16)
x-2 = ±4

Answer:
<h2>(-6)×3ⁿ⁻¹</h2>
Step-by-step explanation:
We notice that in this sequence (an) we multiply by 3 each time to get the next term
e.g : (-6)×3 = -18
then
the commonn ratio q = 3
the first term a1 = -6
the explicit formula :
an = a1×qⁿ⁻¹ = (-6)×3ⁿ⁻¹
Count the distance d, which gives you 7.
Use Pythogarean theorem to find c:
Plug in the numbers:
