Answer: 4x^2-x
Step-by-step explanation:
A=AB*DE=(8+4)*7=12*7=84 m^2
A=84 m^2
Answer:
Step-by-step explanation:
You don't say whether this is compound interest or simple interest.
I will assume it's compounding that interests you.
The appropriate formula is
A = P(1 + r)^t, where r is the interest rate as a decimal fraction, t is the time in years, and P is the original amount. Thus:
A = $1000·(1 + 0.05)^t, or A = $1000·(1.05)^t
Please note: There were apparently possible answer choices. Next time, please be sure to list such choices. Thank you.

Answer:
B. $8,144.47
Step-by-step explanation:
The compound interest formula is ...
A = P(1 +r)^t
where r is the annual rate compounded annually for t years, applied to principal P.
A = $5000(1 +0.05)^10 = $8144.47
After 10 years, there will be $8,144.47 in the account.
Answer:
1. the y-intercept is 9.5 and it means the starting length of the candle
2. the slope is -1/2 and it means that the candle burns 1/2 an inch every hour
3. it burns an inch every 2 hours, it is 9.5 inches long, so 19 hours it'll take to burn.
