X^3 + 7x^2 -6x -42

Take out common factors

x^2(x+7) -6(x+7)

group them together (combine the factors you pulled out, which are x^2 and -6 then group them. x+7 is repeated twice so that can be combined into one factor.

final factors:
(x^2-6) (x+7)

Answer:

= (x=7) x (x-6)

Step-by-step explanation:

x² = 7x - 6x - 42

Factor out x from expression

X squared x (x + 7) - 6x - 42

Factor out -6

X squared x (x + 7) - 6x (x+7)

Factor out x+7

(x+7) x (x-6)

What is 6^-2/2^4 ???????????????​
sergij07 [2.7K]

Answer:

1/52

Step-by-step explanation:

2 to the fourth is 16, and 6 to the second is 36. However, since it's a negative exponent, you'd have to move it down to to the bottom of the fraction, creating 1/16+36, which makes 1/52.

A 47-inch piece of steel is cut into three pieces so that the second piece is twice as
Aneli [31]

Answer:

<h2>                first piece:    5 in</h2><h2>           second piece:   10 in</h2><h2>               third piece:   32 in  </h2>

Step-by-step explanation:

x   - the length of the <u>first piec</u>e

2x    - twice the length of the first piece (the length of the <u>second piece</u>)

6x   - six times the  length of the first piece

two inches more:

6x+2    - the length of the <u>third piec</u>e

first + second + third = 47 in  {total length of the pieces of steel}

x + 2x + 6x + 2 = 47

9x + 2 = 47

9x = 45

x = 45:9

x = 5 in

first piece:   5 in

second piece: 2×5 = 10 in

third piece:   6×5 + 2 = 30 + 2 = 32 in

The Friendly Sausage Factory (FSF) can produce hot dogs at a rate of 5,750 per day. FSF supplies hot dogs to local restaurants a
NARA [144]

Answer:

A) 22812 hotdogs per run

B) 75 runs/yr

C) 4 days in a run

Step-by-step explanation:

We are given;

Production rate;p = 5750 per day

Steady Usage rate;u = 270 per day

Setup cost of hotdog;S = $67

Annual carrying cost (H) = 47 cents = $0.47 per hot dog

No. of Production days; d = 297 days

A) Let's first find the annual demand given by the formula;

Annual demand;D = pd

D = 5750 × 297

D = 1707750 hot dogs/yr

Now, formula for optimal run size is given by;

Q_o = √[(2DS/H) × (p/(p - u))]

Plugging in the relevant values gives;

Q_o = √[(2 × 1707750 × 67/0.47) × (5750/(5650 - 270))]

Q_o =√520375454.7971209

Q_o = 22812 hotdogs per run

B) formula for Number of runs per year is given as;

No. of Runs = D/Q₀

Thus;

no. of runs = 1707750/22812

no. of runs ≈ 75 runs/yr

C) Length of a run is given by the formula;

Length = Q₀/p

Length = 22812/5750

Length ≈ 4 days in a run
