Answer:  4(x^2 + 4)

============================================

Explanation:

The terms 4x^2 and 16 have the factor 4 in common. We can pull factor out using the distributive property

4x^2 + 16 = 4*x^2 + 4*4 = 4(x^2 + 4)

So that's how 4x^2+16 turns into 4(x^2+4)

-----------

further info:

If you want to factor over the complex numbers, then x^2+4 would factor into (x+2i)(x-2i)

though it's not clear if your teacher wants you to do this or not

Sam opened a money-market account that pays 2% simple interest. He started the account with $7,000 and made no further deposits.
Juliette [100K]
Answer:  $7,420.00 = 3 years
(I = A - P = $420.00)

Equation:
A = P(1 + rt)
Calculation:
First, converting R percent to r a decimal
r = R/100 = 2%/100 = 0.02 per year.

Solving our equation:
A = 7000(1 + (0.02 × 3)) = 7420 
A = $7,420.00

The total amount accrued, principal plus interest, from simple interest on a principal of $7,000.00 at a rate of 2% per year for 3 years is $7,420.00.

Which is an arithmetic sequence?
astraxan [27]

Answer: the arithmetic sequence is

3, 10, 17, 24

Step-by-step explanation:

In an arithmetic sequence, the consecutive terms differ by a common difference. This means that the difference between the first term and the second term must equal the difference between the second term and the third term.

Considering the following sequences,

1) 4 - 1 = 3

9 - 4 = 5

There is no common difference and so, it is not an arithmetic sequence.

2) 10 - 3 = 7

17 - 10 = 7

The common difference is 7. So it is an arithmetic sequence.

3) 6 - - 5 = 11

10 - 6 = 4

There is no common difference and so, it is not an arithmetic sequence.

4) 2 - 1 = 1

4 - 2 = 2

There is no common difference and so, it is not an arithmetic sequence.
