I will gladly simplify it.
9k - 6k + 7k - 8
9k - 6k = 3 k
3k + 7k - 8
3k + 7k= 10k
10k - 8 = 2k
So the simplified form of 9k - 6k + 7k - 8 is 2k

Answer:
100,000,000
Step-by-step explanation:
You can just add up the zeros, if that makes sense.
length is 8m
Width is 6.5m
<u>Explanation:</u>
Let, width = b
So, length = 2b-5
area = 52
We know,
area of rectangle = length X width
So,
= 
On solving the above equation, we get
Width, b = 6.5m
length, l = 8m
Answer:
135
Step-by-step explanation:
subtract 180 by 45 since a line is 180, that is what you get for the angle that is adjacent to angle 2, there is a rule if it is adjacent, they equal each other. thus, angle 2 is 135
