Answer:
Step-by-step explanation:
if its x to the second power:
(3)^2-5(3)+8= 9-15+8=17-15=2
if it is 2x
2(3)-5(3)+8=6-15+8 =-1

Step-by-step explanation:</h3>
1. Each year the balance is multiplied by 1.09, so after 5 years, the balance is multiplied by 1.09^5 ≈ 1.53862395. Subtracting the original invetment amount gives the value of the interest earned.
... 5000 × 1.53862395 - 5000 = 5000 × 0.53862395
... ≈ 2693.12 . . . . matches choice D
2. The interest earned is given by the formula ...
... I = Prt . . . . . where P is the principal, r is the interest rate, and t is the time period.
Filling in the given numbers, you have ...
... I = 2500×0.085×10 = 2125 . . . . matches choice B
3. The product of length and width is the area. If both length and width are multiplied by 3.2, then the area is multiplied by 3.2×3.2 = 10.24. The appropriate choice is B.
Answer: x = 2/7
