To solve we have to write 12x as 2x+10x
<span><span>x2</span>+2x+10x+20</span>
taking x and 10 as a common
x(x+2)+10(x+2)
now (x+2) is common
<span>(x+2)(x+10) answer</span>
Your question is incomplete.
3 Metres; because for each 100 centimetres there is one metre. With centi- being the prefix for 10^-2 in the metric system.
The mean of the answer is 20.5 because you add all of the number together and divide by 6 because there's 6 numbers.
I'm sorry, but I don't know how to do the standard deviation...
Hope this helped!
Answer: 225km
Step-by-step explanation:
3cm --- 150
