Hi again :)
5b^3(4 - 9b^2)
Use the distributive property
=(5b^3)(4) + (5b^3)(-9b^2)
= 20b^3 - 45b^5
= -45b^5 + 20b^3
Have a nice day!
1 hour = 3 gallons
15 hours = 3 x 15 gallons
15 hours = 45 gallons
Answer:
No, This is not reasonable estimate.
Step-by-step explanation:
Charles wants to take out a 5 year loan on car that cost $15000.
He make rough estimate to make payment. He can afford to pay up to $200 per month.
First we find total number of months in 5 years.
Total months = 5x12= 60 months
Total estimate to pay = =$12000
we can see cost of a car $15,000 is greater than his estimation $12,000.
Therefore, Charles estimation will not work.
No, This is not reasonable estimate.
