8 0

Answer:

The set of solution is {-9,-4}

Step-by-step explanation:

*  We use this result: A.B=0 , that means A=0 or B=0.

*  (x+9)(x+4)=0, then x+9=0 or x= - 9

Or x+4=0, x= - 4.

This equation has 2 solutions: - 9 and - 4.

Hope that useful for you.

Nathan opens a new savings account and makes an initial deposit of $400.
AfilCa [17]

Answer:

The answer to the first one is 6

Step-by-step explanation:

If the time frame given is 9 months, then we can find that 9 months is 3/4 of a year. 3/4 x 2% = 0.015.     0.015 x 400 = 6. He would have made 6 dollars in 9 months.

Answer the the second one:

4.5% x 5 (years) = 0.225.     0.225 x 10,000 = 2,250. Since this is a car loan and not a bank interest for example, we add it to the total cost. I'm pretty sure its the third one.

tino4ka555 [31]

Answer:

4x^{2}-16x+8
