Answer:
4.1n
Step-by-step explanation:
Let's simplify step-by-step.
n−4.6n−3.3n+2.8n
=n+−4.6n+−3.3n+2.8n
Combine Like Terms:
=n+−4.6n+−3.3n+2.8n
=(n+−4.6n+−3.3n+2.8n)
=−4.1n
Answer:
Step-by-step explanation:
okay, so here are a few methods you can use.
___
1) +
x + 7 = 10 so because this is addition we use the reverse, subtraction. So
x - 7 = 10 - 7 and that equals to 3.
2) -
x - 2 = 10 so because this is subtraction we do the reverse, addition.
x + 2 = 10 + 2 and that equals to 12.
3) x
x times 3 = 21 because this is multiplying we divide.
x/3 = 21/3 and that would be 7.
4) /
x/2 = 10 same as above, reverse is multiplying.
x times 2 = 10 times 2 and thats 20.

Answer: Bottom left corner
Let n be an odd number. Because 4n is a multiple of 2, it is an even number.
============================================
Explanation:
The square has a side length of n, so its perimeter is 4n since n+n+n+n = 4n.
We can rewrite 4n as 2*2n = 2m where m = 2n is an integer. Any number in the form 2*(some integer) is always even. Even numbers always have 2 as a factor.
So whenever it comes to proving something is even, the ultimate goal is to get it into the form 2*(some integer). If we can do this, then the number is even. If not, then the number is odd.
