The area of a rectangle is (x3 – 5x2 + 3x – 15), and the width of the rectangle is (x2 + 3). If area = length × width, what is t
lisabon 2012 [21]

Answer:

D

Step-by-step explanation:

The area of a rectangle is given by the formula:

A=lw

So, we are given that the area is:

x^3-5x^2+3x-15

And the width is:

x^2+3

And we want to find the length. To do so, first substitute the expressions into the equation:

x^3-5x^2+3x-15=(x^2+3)l

Thus, to find the length, divide by (x²+3):

l=\frac{x^3-5x^2+3x-15}{x^2+3}

So, factor the numerator:

x^3-5x^2+3x-15

From the first two terms, factor out a x^2.

From the third and fourth terms, factor out a 3:

=x^2(x-5)+3(x-5)

Combine:

=(x^2+3)(x-5)

Putting this back:

l=\frac{(x^2+3)(x-5)}{x^2+3}

Cancel:

l=x-5

And that's our answer :)

I believe it would be D.

That reminds me, I have to go check if my kid's tent is ready for camp.

The volume of this triangular prism tent will be the area of its base times its length, six feet here.   The area of the triangle is of course half the base times the height.

If we call the height h we get 

36 = (1/2) (4)(h)(6)

36 = 12 h

h = 3 feet

Most folks can sit in a 3 foot tall space, but it's a little tight, especially with your head squeezed up there near the apex.

masya89 [10]

Answer:

13/52

explanation:

If you have a regular set of 52 two cards and you pulled 3 cards at random from the deck you would have a 13/52 chance or a 25% chance of pulling cards that are hearts. Due to the fact that card sets have 13 heart cards.
