6,395.00 x 2 = 12,790
So $12,790 for the emerald rings.
5,314.00 x 2 = 10,628
So $10,628 for the pearl bracelets.
12,790 + 10,628 = 23,418
So $23,418.00 for all four pieces of jewelry.
Hope it helps!

Step-by-step explanation:
f(x) = x² + 1
f(2) = (2)² + 1
= 4 + 1
= 5
Answer:
3
Step-by-step explanation:
Calculate the distance d using the distance formula
d = 
with (x₁, y₁ ) = (5, 4) and (x₂, y₂ ) = (- 1, 1)
d = 
= 
= 
= 
= 3 ← exact value
≈ 6.71 ( to 2 dec. places )
We can use completing the square.We add 16 and subtract 7 to both sides. Now we get m^2+8m+16=9. The left sides becomes (m+4)^2=9. Taking the square root of both sides and subtracting 4 we get -1 and -7.
