Which expression is equivalent to 4x2 - 4x – 3 in factored form?

erastovalidia [21]

Answer:

(2x-3)(2x+1)

Step-by-step explanation:

4x^2 - 4x - 3

we need two numbers that give 12 when multiplied and 4 when subtracted

the numbers are 6 and 2 because 6*2=12 and 6-4=4.

4x^2 - (6-2)x -3

4x^2 -6x +2x -3

take common

2x(2x -3)+1(2x-3)

take (2x-3) as common

(2x-3)(2x*1 + 1*1)

(2x-3)(2x+1)

Compute the total and annual return on the following investment Two years after paying 53500 for shares in a startup company you

wel

Answer:

-46.91%

Step-by-step explanation:

Given:

Cost of buying the shares = $53,500

Selling cost of the shares = $3,300

Number of years = 2

Since the selling cost is less than the buying cost, therefore the statement for the loss can be verified

Now,

The loss = Selling cost - cost of buying = $3,300 - $53,500 = - $50,200

thus, the loss per year = $\frac{\textup{50,200}}{\textup{2}}$ = -$25100

Hence,

Rate of return = $\frac{\textup{Loss per year}}{\textup{Cost of buying}}\times100$

or

Rate of return = $\frac{\textup{-25100}}{\textup{53,500}}\times100$

or

Rate of return = -46.91%

What is the volume of a cylinder with a height of 3 feet and a radius of 4 feet use 3.14 for pi

Vlad1618 [11]

Answer:

$\large\boxed{V\approx150.72\ ft^3}$

Step-by-step explanation:

The formula of a volume of a cylinder:

$V=\pi r^2H$

r - radius

H - height

We have the height H = 3ft and the radius r = 4ft. Substitute:

$V=\pi(4^2)(3)=\pi(16)(3)=48\pi\ ft^3$

$\pi\approx3.14$

$V\approx48(3.14)=150.72\ ft^3$

x * x = x^2

x * .7 = .7x

-6 * x = -6x

-6 * .7 = -4.2

x^2 + .7x - 6x -4.2

x^2 - 5.3 - 4.2

x = 6
