Find the difference. Write your answer in standard form. ( 3x3 + x-4) - (4x² + 2x - 5) The difference is?

lukranit [14]

Answer:

Step-by-step explanation:

3x³ + x - 4 - (4x² + 2x - 5) = 3x³ + x - 4 - 4x² - 2x + 5

Now combine like terms

= 3x³ - 4x² + <u>x - 2x</u> <u>- 4 + 5</u>

= 3x³ - 4x² -x + 1

Need help with math homework

Hello!

The answer for A is:

$X1=-1\\X2=5$

The answer for B is: The rocket will hit the lake surface in 5 seconds.

Defining the terms:

$a=-16\\b=64\\c=80\\$

So, replacing it in the quadratic equation (it's given to you in the exercise)\\

$x=\frac{-b+-\sqrt{b^{2}-4*a*c } }{2*a}$

$x=\frac{-64+-\sqrt{64^{2}-4*-16*80 } }{2*-16}$

$x=\frac{-64+-\sqrt{64^{2}+5120} }{-32}=\frac{-64+-\sqrt{4096+5120} }{-32}\\x=\frac{-64+-\sqrt{9216} }{-32}=\frac{-64+-\ 96 }{-32}\\x=\frac{-64+-\ 96 }{-32}\\x1=\frac{-64+\ 96 }{-32}=\frac{32}{-32} =-1\\\\x1=\frac{-64-\ 96 }{-32}=\frac{-160}{-32} =5\\$

We are working with a quadratic equation, so we will have two possible results,

$X1=-1\\X2=5\\$

Now, we are asked to find the time, time can not be a negative value, we have to discard X1 (-1) since it's a negative value, knowing that, the rocket will hit the lake after 5 seconds.

Have a nice day!
