Answer:
-4x^2 + 237x - 675
Step-by-step explanation:
(x - 3)*(232 - 4x -7) >> Distribute x and -3 to the trinomial
232x - 4x^2 - 7x - 696 + 12x + 21 >> Simplify
-4x^2 + 237x - 675

Step-by-step explanation:
Answer:
$333.17
Step-by-step explanation:
Use the compounding formula
![A(t)=P(1+r)^t](https://tex.z-dn.net/?f=A%28t%29%3DP%281%2Br%29%5Et)
where A(t) is the amount at the end of the compounding,
P is the initial deposit,
r is the interest rate in decimal form, and
t is the time in years.
Filling in our info:
![A(t)=180(1+.08)^8](https://tex.z-dn.net/?f=A%28t%29%3D180%281%2B.08%29%5E8)
Simplify a bit to
![A(t)=180(1.08)^8](https://tex.z-dn.net/?f=A%28t%29%3D180%281.08%29%5E8)
Raise 1.08 to the 8th power and get
A(t) = 180(1.85093021) and then multiply to get
A(t) = $333.17
