Answer:
So this is scientific notation what you do is
2.9x10^5 so you put however many zeros the is powered to 10. See there is a 5 It has to be behind or in front of the decimal you might be saying how do you know if its behind or in front well negative is in front and positive is behind .
<u><em>290,000 </em></u>there was a number already behind the decimal so there you go 5 number behind the decimal.
Same for the second one
<u><em>290,000</em></u><em> </em><u><em>870,000</em></u> is your answers so now you add hem together
<em><u>1,160,000 is your final answer </u></em>
Step-by-step explanation:
(2x + 1)³
(2x + 1)(2x + 1)(2x + 1)
(4x² + 2x + 2x + 1)(2x + 1)
(4x² + 4x + 1)(2x + 1)
(8x³ + 4x² + 8x² + 4x + 2x + 1)
8x³ + 12x² + 6x + 1
Should be 10, or 9.65606. Hope this helps!
