An oak tree is 1.5×1031.5×103 centimeters tall. Which unit of measurement is most appropriate to measure this height?

1 answer:

3 0

If you multiply the amount that you give 1.5 × 1031.5 × 103 the result is 159366.75 centimeters, which is very long to write. For better understanding it is preferable that you write the answer to this multiplication in kilometers. Which would give a result of 1.59 kilometers

Answer:

$\rm{-2$

Step-by-step explanation:

Hi there!

$\rm{-4(t+4)=-8t-24}$

$\rm{-4t-16=-8t-24$

$\rm{-4t+8t=-24+16$

$\rm{4t=-8$

$\rm{-2$

Thus, $-2$ is our final answer.

Hope it helps! Enjoy your day!

(5-x)(5+x)=(x-4)²-7<br> Helpp((

hoa [83]

$\displaystyle\\
(5-x)(5+x)=(x-4)^2-7\\\\
5^2 - x^2 = x^2-8x + 16 -7\\\\
-x^2 -x^2+8x + 25 -16+7=0\\\\
-2x^2 + 8x +16=0\\\\
x_{12}= \frac{-b\pm \sqrt{b^2-4ac} }{2a}= \frac{-8\pm \sqrt{64-4\cdot(-2)\cdot 16} }{2\cdot(-2)}=\\\\
 = \frac{-8\pm \sqrt{64+ 128} }{-4}= \frac{-8\pm \sqrt{192} }{-4}= \frac{-8\pm \sqrt{64\cdot 3} }{-4}=\\\\
=\frac{-8\pm 8\sqrt{ 3} }{-4}=2\mp 2\sqrt{ 3}\\\\
\boxed{\bf x_1 = 2-2\sqrt{ 3}}\\\\
\boxed{\bf x_2 = 2+2\sqrt{ 3}}$
