What are the factors of the following quadratic equation 12=x^2-x

1 answer:

8 0

12 = x² - x
12 - 12 = x² - x - 12
0 = x² - x - 12
x² - x - 12 = 0
x = -(-1) +/- √((-1)² - 4(1)(-12))
 2(1)
x = 1 +/- √(1 + 48)
 2
x = 1 +/- √(49)
 2
x = 1 +/- 7
 2
x = 0.5 +/- 3.5
x = 0.5 + 3.5 x = 0.5 - 3.5
x = 4 x = -3

Given:

The given figure is a square pyramid.

The side length of the base of the pyramid is 6.6 feet.

The height of the pyramid is 12.672 feet.

We need to determine the volume of the pyramid.

Area of the base:

The area of the base can be determined using the formula,

$A=a^2$

where a is the side length of the base.

Substituting a = 6.6, we get;

$A=6.6^2$

$A=43.56 \ ft^2$

Thus, the area of the base is 43.56 square feet.

Volume of the pyramid:

The volume of the pyramid can be determined using the formula,

$V=\frac{1}{3}Ah$

where A is the area of the base and h is the height of the pyramid.

Substituting A = 43.56 and h = 12.672, we get;

$V=\frac{1}{3}(43.56)(12.672)$

$V=184 \ ft^3$

Thus, the volume of the pyramid is 184 cubic feet.

Answer:

$\frac{6}{x} = \frac{4}{8}$

Multiple across equal sign (Denominator x Nominator and vise versa)

$4x = 6 \times 8$

$4x = 48$

$x = 48 \div 4$

$x = 12$

It is important to keep the same tense in your business writing, because otherwise your readers may ______.

Goshia [24]

It is important to keep the same tense in your business writing, because otherwise your readers may misinterpret what you are trying to convey. Not having a uniform form of tense would make the writing confusing for the reader. Hope this helps. Have a nice day.
