Recall that zeroes can be transformed into factors by subtracting them from x. This gives us the following factors:

(x - 1)(x + 3)(x - 4)

Now, if you multiply the first two factors together, you get the following:

(x² + 2x - 3)

Multiply that by the last factor, (x - 4), and you get this:

(x³ + 2x² - 3x - 4x² - 8x + 12)

This can be simplified:

(x³ - 2x² - 11x + 12)

And there's your final answer. Hope this helped!

Answer:

The temperature at midnight is -12 degree Celsius

Step-by-step explanation:

Given -

Temperature at 6:00 PM = -20 degree Celsius

Let the temperature at midnight be X degree Celsius

From midnight to 6:00 am, the temperature rose by 8 degree Celsius

X - (-20) = 8

X = 8-20

X = -12 degree Celsius.

The temperature at midnight is -12 degree Celsius.

The following section is a statement from the rental agreement Tim signed when he rented his car this past weekend.
vitfil [10]

Answer:

b.   $31.44

Step-by-step explanation:

The tank holds 11.75 gallons.  Tim will need to get half of this amount to bring the tank back up to half full; this is

11.75/2 = 5.875

The gas costs $4.50 per gallon; this means the cost is

5.875(4.50) = 26.4375 ≈ 26.44.

There is also a $5 refueling charge; this makes the total cost

26.44+5 = 31.44

Explain how to find the zeros of the given polynomial: x3+3x2–x−3<br><br> What are the zeros?
AveGali [126]

Answer:

Step-by-step explanation:

The zero (root) of a function is any value of the variable that will produce an answer of zero. Graphically, the real zero of a function is where the graph of the function crosses the x-axis.

~~~~~~~~~

f(x) = x³ + 3x² - x - 3

f(-3) = ( - 3 )³ + 3( - 3 )² - ( - 3 ) - 3 = 0

f(-1) = ( - 1 )³ + 3( - 1 )² - ( - 1 ) - 3 = 0

f(1) = ( 1 )² + 3( 1 )² - ( 1 ) - 3 = 0

Help I will be marking brainliest!!
lora16 [44]

Answer:

<u>Given</u>: base = 10.4ft, height = 12.5

Area of octagon = 8(1/2 × b × h)

  • 8(1/2 × 10.4 × 12.5)
  • 520ft²

Volume of pool = 520ft² × 3ft

  • 1560ft³

Now, 1 cubic ft takes 7.5 gallons to fill.

Therefore, 1560 cubic ft takes,

  • 1560 × 7.5
  • 11700

So, <u>Correct choice</u> - [D] 11,700.
