Factor the polynomial function over the complex numbers.
Bumek [7]

Answer:

[x - 1][x + 1][{x}^{2} + 4]

Step-by-step explanation:

Knowing that you have to find two numbers that when they differ to 3, they also multiply to −4, and those numbers are −1 and 4. So, after clearing that up, you will have this [since our degree of this polynomial function is 4]:

[{x}^{2} - 1][{x}^{2} + 4]

Then, since {x}^{2} - 1 is factorable, you will get this:

[x - 1][x + 1]

Finally, attach [{x}^{2} + 4] to the partially factored polynomial to get this:

[x - 1][x + 1][{x}^{2} + 4]

I am joyous to assist you anytime.

What should we subtract from 50/29 to get 24
Scrat [10]

Answer:

-22.28

Step-by-step explanation:

Let the number to be subtracted from 50/29 to get 24 to be x

So this can be written as : 50/29 - x =24 ----collect like terms as

50/29 - 24 = x

1.72 -24 = x

-22.28 = x

So to check the answer;

50/29 -{x} = 24

50/29 - {- 22.28} = 24

1.72+ 22.28 = 24 ---correct.

The area of the sandbox is 56 2/3 square feet. The width is 8 1/2 feet. What is the length? Hint: Divide area by length
sertanlavr [38]

Answer:

20/3 ft or 6 2/3 ft

Step-by-step explanation:

A = 56 2/3 sq ft

W = 8 1/2 ft

L = ?

A = LW

L = A/W

L = \dfrac{A}{W}

L = \dfrac{56~\frac{2}{3}~sq~ft}{8~\frac{1}{2}~ft}

Change the mixed numbers into fractions.

a\frac{b}{c} = \dfrac{ac + b}{c}

L = \dfrac{\frac{56 \times 3 + 2}{3}}{\frac{8 \times 2 + 1}{2}}

L = \dfrac{\frac{170}{3}}{\frac{17}{2}}

L = \dfrac{170}{3} \div \dfrac{17}{2}

L = \dfrac{170}{3} \times \dfrac{2}{17}

L = \dfrac{170 \times 2}{3 \times 17}

L = \dfrac{17 \times 10 \times 2}{3 \times 17}

L = \dfrac{10 \times 2}{3}

L = \dfrac{20}{3}

Answer: 20/3 ft or 6 2/3 ft
