(12x3 - 14x2 - 40x) / (2x-5)
 Rewriting we have:
 (2x (2x-5) (3x + 4)) / (2x-5)
 We simplify similar terms:
 2x * (3x + 4)
 We rewrite:
 6x2 + 8x
 Answer:
 
The simplified expression is given in this case by:

There is 6-9 for the people that confused
Alina [70]

Answer:

6. 75 Students in Mrs.Reynolds class.

7. 60 Birthdays in February

8. February and May are a combined 20% of birthdays

9. March has 24% of the students birthdays

Step-by-step explanation:

6.   Adding all the numbers will give us 75 total students.

7.   450 divided by 7 will get us 6. And there are 10 birthdays in February, so we do 10 times 6 and get 60.

8.   On a calculator if you input 20% of 75 you will get 15. February and May are the only 2 birthday months that if you add them up you get 15.

9.   If you put 24% of 75 on a calculator you will get 18. March is the only month with 18 birthdays.

Samantha is evaluating whether to increase production at her book bindery. If she hires one more worker, she can increase output
natima [27]

Answer:

Samantha's marginal cost of increasing output by 50 books per week is $5

Step-by-step explanation:

Marginal cost is given as change in cost divided by change in quantity produced

change in cost (weekly wage) = $250

change in quantity produced weekly = 50 books

Marginal cost = $250 ÷ 50 = $5

Her marginal cost is $5 per week

HELP :(
Marina CMI [18]

There is 1 solution, which is 3/4.

To show this, you actually have to solve the equation. First, you distribute -1 into(9 - 3h) and distribute -3 into (h + 2). In doing so, you should be left with "6h - 9 + 3h = 6 - 3h - 6". Next you combine like terms on each side, so you add 3h to 6h and you subtract 6 from 6. Now you should have "9h - 9 = -3h". Then, you start to solve by subtracting 9h from both sides. You should have -9 = -12h, which you divide -12 on both sides to get h by itself. Finally, you have h = 9/12 (since the negatives on the top and bottom cancel out) which simplified (divided by 3/3) is 3/4. Thus meaning there is only 1 answer.

I hope this helps!
