Answer:
6(8x-3)x(3x²-7)
Step-by-step explanation:
144x³-54x²-336x+126
=6(24x³-9x²-56x+21)
=6(3x²x(8x-3)-7(8x-3))
=6(8x-3)x(3x²-7)
First simplify the one inequality, 6r + 30 greater than or equal to 12 just divide by 6 then subtract 30 from both sides of the inequality. You should get r is greater than or equal to -3. For this one you need to reverse the inequality symbol then divide both sides by -1 to get a positive r, and you get r is less than -12. It's not A because there's two solutions, and it's not D for the same reason. It's not C because r isn't greater than -12. In conclusion it's B because it correctly represents the solutions that make the inequality true. I hope this helps you on your high school application :)
Answer:
Thus the length = 230 and width = 90.
Step-by-step explanation:
Farmer Fernanda wants to put a fence around her rectangular field. The length of the field is 40 feet less than 3 times the width.
She has 320 feet of fencing.
Let the length of the rectangular fence be x and the width of the fence be y.
Then the relation between them is
x = 3y - 40
Also x + y = 320
Solving these equations,
320 - y = 3y - 40
4y = 360
y = 90
x = 230
Thus the length = 230 and width = 90.
Quotient Rule. Objectives: In this tutorial, we derive the formula for finding the derivative of a quotient of two functions and apply this formula to several examples. After working through these materials, the student should be able to derive the quotient rule and apply it.

There are 10 trucks and 18 tractors
I found that out by multiplying 10 and 1.8 which gave me 18
when u add 10 and 18 u get 28
