Answer:
x² - 3x + 5 - [24÷(x+3)]
Step-by-step explanation:
1. Expand (x³ + 2x - 6x - 9)
= x³ - 4x - 9
2. Divide [x³ - 4x - 9 by x+3]
= x² + [(-3x^2-4x-9) ÷ (x+3)]
3. Divide [(-3x^2-4x-9) by (x+3)]
= -3x + [(5x-9) ÷ (x+3)]
x² - 3x + [(5x-9) ÷ (x+3)]
4. Divide [(5x-9) ÷ (x+3)]
= 5 + [(-24) ÷ (x+3)]
x² - 3x + 5 + [(-24) ÷ (x+3)]
= x² - 3x + 5 - [24 ÷ (x+3)]
I think it’s C, good luck
Answer: 16 pi or ≈50.27
Explanation: Formula for a cylinder:
V = pi r ^2 h
V = pi (2)^2 4
V = 4 pi (4)
V = 16pi
Answer:
Solution = (-8,-28)
Step-by-step explanation:
Answer:
$424
Step-by-step explanation:
Find area of all surfaces to be covered
20 x 30 = 600 ceiling
10 x 20 = 200 x 2 = 400 two walls
10 x 30 = 300 x = 600 other two walls
Assume no doors
total area is 1600 square feet
multiply by 2 because you are doing two coats
3200 total area to be covered
3200/400 = 8 gallons of paint x $53 = $424
