When we cube root 123, we get a decimal which rounds out to 4.97. So possible side lengths would be any number greater than that.<span />
Answer:
-1078
Step-by-step explanation:
To find the nth term in an arithmetic sequence we use the following formula
aₙ=a₁+(n-1)*d
Where a₁ is the first time, and d is the common difference (in this case -20)
So we have
2+(55-1)*-20
2+(54)*-20
2-1080
-1078
Answer:

(2f^2-2^2)
Answer:
x > 367
Step-by-step explanation:
set x = # of DVDs they sold
Each DVD costs $15 so the total amount they made is 15x
Since they raised more than $5500
15x > 5500
Divide both sides by 15 to solve the inequality and you get
x > 366.67 and since you can't sell 0.67 of a DVD, round up to get
x > 367 which means that they sold more than 367 DVDs
