Area = length times width

A = (3x^2 - 4x + 6)(x - 6)

A = 3x^3 - 4x^2 + 6x - 18x^2 + 24x - 36

A = 3x^3 - 22x^2+ 30x - 36

Done!

At least they admitted this is algebra not geometry. You'll get the same question next year but they'll call it geometry.

The area is the product of the sides:

A=(x-6)(3x^2-4x+6)

We just distribute and collect terms:

A=x(3x^2-4x+6) - 6(3x^2-4x+6)

A=3x^3-4x^2+6x - 18x^2 +24x -36

A=3x^3- 22x^2+30x-36

Answer: 3rd choice

Many poker games start with each player being dealt five cards, called the player's "hand". Remember, there are 52 cards in a st
jek_recluse [69]

Answer:

The number of different possible poker hands is found by counting the number of ways that 5 cards can be selected from 52 cards, where the order is not important. It is a combination, so we use c n r

Step-by-step explanation:

The possible number of the poker hands is probably . C 52 5= 52!/5!x47!= 2598960

In the formula l=p+prt, what does l equal when p=500,r=20%, t=2
Juliette [100K]
Just plug in 500 for p, 0.2 for r (because 20% is equivalent to 0.20), and 2 for t:

I=p+prt\\I=(500)+(500)(0.2)(2)\\I=500+200\\I=700

So, if you start with $500 and charge an interest rate of 20% for 2 years, you will gain $200 to get $700 in total.

which equation is the quadratic variation equation for the relatonship? the variable y varies directly with x^2 and y=36 when x=
svetoff [14.1K]

For this case we have a direct variation of the form:

y = kx ^ 2

Where,

  • <em>k: proportionality constant </em>

We must find the value of k.

For this, we use the following data:

y = 36\\x = 3

Therefore, replacing values we have:

36 = k (3) ^ 2

Rewriting:

36 = 9k

Clearing the value of k we have:

k = \frac {36} {9}\\k = 4

Therefore, the direct variation equation is given by:

y = 4x ^ 2

Answer:

The quadratic variation equation for the relatonship is:

y = 4x ^ 2

Find the hypotenuse of an isosceles right triangle when the legs each measure 3\sqrt{x} 2inches.
Tresset [83]

The hypotenuse of the right triangle measures 3 units.

<h3>How to find the hypotenuse?</h3>

Here we know that both legs measure:

L  =\frac{3}{\sqrt{2} }

If we use the Pythagorean theorem, we will see that the hypotenuse H can be written as:

H^2 = (\frac{3}{\sqrt{2} } )^2 +  (\frac{3}{\sqrt{2} } )^2 \\\\H^2 = \frac{9}{2} + \frac{9}{2} = \frac{18}{2} = 9\\\\H = \sqrt{9} = 3

Then we conclude that the hypotenuse of the right triangle measures 9 units.

Transform this equation to slope-intercept form: 6x + 4y = 8
JulsSmile [24]
Basically, ur just solving for y

6x + 4y = 8...subtract 6x from both sides
4y = -6x + 8....now divide both sides by 4
y = (-6/4)x + 8/4...reduce
y = -3/2x + 2 <=== slope intercept form
