Answer:
Assuming you want to simplify the expression, it can be shortened to:
-k² - 2k
Step-by-step explanation:
What you need to do here is called grouping like terms. Like terms can be described as terms that have the same factors. In this case, the factors we're looking at are k and k²:
Given:
k - 3k² -3k + 2k²
We'll rearrange to group like expressions:
= -3k² + 2k² + k -3k
Pull out common factors:
= (-3 + 2)k² + (1 - 3)k
And simplify:
= -k² - 2k
Answer: 37
Step-by-step explanation:
<span> 16501
(10^23) • 16501/5000
</span><span> 2.1 10 = 2•5
</span>
<span>(10)^23 = (2•5)^23 = 2^23 • 5^23</span>
<span> 16501
(2^23•5^23) • 16501/5000
</span>
Answer:
I tried everything and either I'm doing it wrong or you wrote this wrong
Step-by-step explanation:
Alright, lets get started.
Jim was thinking of a number.
Suppose the number Jim was thinking, is x.
Jim adds 20 to it means number will be = 
And Jim doubles it, means 
Jim gets 99.2 and as per us, he gets 
So, making them equal


Subtracting 40 in both sides



It means the original number is 29.6. : Answer
Hope it will help :)
