Answer:
(42-24n)
Step-by-step explanation:
(7-4n)×6
take the 6 and multiply it to the integers in the paraenthesis.
so you take the ouside number which is 6 and multiply it with the first number which is 7 in the paraenthesis.
6×7=42
(42-4n)
then take the next number 4n and multiply by 6
4n × 6 = 24n
finally put it all together
(42-24n)
sorry if that didnt help
Answer:
Basically you plug the numbers in. x=-2, so it would be 3(-4+1)^3. That can be simplified to -81, e. Please give Brainliesttt!!!!

Answer:
The bottom boxes should be $100, $150, $200, $250, $300. The top box should be 8.
Step-by-step explanation:
So, at time 0 you only pay the rental fee of $100 (no time has passed yet). At 1 hour, it is $100 plus the $50 per hour rental fee. At 2 hours, it would then be $100+$100=$200. At 3 hours, it is $100+$150=$250. And at 4 hours, it is $100+$200=$300. By 8 hours, your fee is $100+$400=$500.
Solve for the two velocities:
with the current = 48/6 = 8 mph
against the current = 48/8 = 6 mph
bv= boat velocity in still water
cv = current velocity
A) bv -cv = 6mph
B) bv + cv = 8mph
Adding both equations
2 * bv = 14 mph
boat velocity = 7 mph
current velocity = 1 mph
