Answer:

24702x + 9

Step-by-step explanation:

First, put everything you need to in parenthisis.

(2x^4) + (12x^4) + (16x^3) - (12x^2) - (18x + 9)

Then Simplifly

32x + 20736x + 4096x - 144x -18x + 9

Now Simplifly everything one by one

20768x + 4096x - 144x - 18x + 9

24864x - 144x - 18x + 9

24720x - 18x +9

24702x + 9

Now you can stop there, or solve for X by dividing each # by 24702

Suppose your grandparents put $500 into an investment that earns 12% interest each year. How much, to the nearest cent, will be
SashulF [63]

Answer

After the 10 years with accrued interest, there will be roughly $1,552.92 in the account.

Explanation

Using the given equation A = P(1 +r)^t

We are given that our initial start is $500.

P = 500

We are further told that the percentage interest gained is 12%, so we need to convert this into a decimal to be able to work with it.

12% / 100% = 0.12

r = 0.12

t is then our time in years

t = 10

A = 500(1 + 0.12)^10

A = 500(1.12)^10

A = 500(3.1058)

A = 1,552.92

After the 10 years with accrued interest, there will be roughly $1,552.92 in the account.
