Answer:  b) 2x² - 5x - 3

<u>Step-by-step explanation:</u>

Distribute each term in the first parenthesis into the second term and then add like terms.

  (2x + 1)(x - 3)

= 2x(x - 3)    +   1(x - 3)

= 2x² - 6x    +    x - 3

= 2x²        - 5x      - 3

sineoko [7]
I think this problem gave the data for the radius of earth so that we will know the conversion ratio between statute miles and nautical miles. However, you can simply search that. There are 1.15 statute miles in 1 nautical mile. Hence,

Distance in nautical miles = <span>884884 statute miles * 1 nautical mile/1.15 statute miles
<em>Distance =769,464.35 nautical miles</em></span>

Can someone please help me with math
vodka [1.7K]

Answer:

B

Step-by-step explanation:

Hey There!

they are asking for the equation in slope intercept form

Slope intercept form is y=mx+b

where m equals slope and b equals y intercept

to find the slope we do change in y over chang in x

as y goes up 2 x goes down 5 so the slope would be -2/5

the y intercept is at (0,4) so the y intercept is 4

now we add everything together and get that the equation in slope intercept form is

y=-2/5x+4

so we can conclude that the answer is B

What is the remainder when (3x3 â€"" 2x2 4x â€"" 3) is divided by (x2 3x 3)?.
melamori03 [73]

The remainder of the equation is \rm 28x+30.

Given that,

When the equation \rm 3x^3-2x^2+4x-3 is divided by \rm x^2+3x+3.

We have to find,

The remainder of the equation?

According to the question,

The equation \rm 3x^3-2x^2+4x-3 is divided by \rm x^2+3x+3.

On the division of the polynomial, the remainder is,

\dfrac{\rm 3x^3-2x^2+4x-3}{\rm x^2+3x+3}

Factorize the equation to convert this into the simplest form,

\rm 3x^3-2x^2+4x-3\\\\3x^3-11x^2+9x^2+9x+28x-33x-33+30\\\\Taking \ the \ common \ terms \ and \ simplify\  the\  equation\\\\3x^3+9x^2+9x+11x^2+33x-33+28x+30\\\\3x(x^2+3x+3) - 11(x^2+3x+3) + 28x+30\\\\(3x+11) (x^2+3x+3) +28x +30

Now, the equation can be written as,

\rm = \dfrac{(3x+11) (x^2+3x+3) +28x +30}{ x^2+3x+3}\\\\=  \dfrac{(3x+11) (x^2+3x+3) }{ x^2+3x+3} + \dfrac{28x +30}{ x^2+3x+3}\\\\= (3x+11)   + \dfrac{28x +30}{ x^2+3x+3}\\\\

The relation between the divisor, remainder, and quotient is,

\rm = Quotient + \dfrac{Remainder}{Divisor}

On comparing with the equation,

The remainder becomes 28x +30.

Hence, The required remainder of the equation is \rm 28x+30.
