Answer:
Add 64
Step-by-step explanation:
x^2 - 16x
<em><u>If you add 64, you get x^2 - 16x + 64 which factors as (x - 8)^2</u></em>

Answer: Add 64
Answer:
81%.
Step-by-step explanation:
To find the average attendance, you will need to find the the total of the average attendance from all 10 days.
Since we know the average attendance of the first 4 meetings was 75%, we can simply assume that those 4 days had this attendance. For this, you can do:
4×75= 300.
Now, for the remaining 6 days, you will need to multiply 85% by the amount of days. 6×85= 510.
Now, to find the average, we will need to add these together:
300+510= 810...
Then divide the result from the total number days to find the AVERAGE:
810÷10= 81%.
Answer: Option 'E' is correct.
Step-by-step explanation:
Since we have given that
If the length of one piece of rope is 2.8 meters shorter than the length of the other.
Let the length of first piece be 'x'.
Let the length of second piece be 'x-2.8'
Total length of rope = 20.6
So, According to question, it becomes,

So, the greatest number of the length of part of rope is 11.7 m.
Hence, Option 'E' is correct.
1) P=2w +2l
46=2w +14
32=2w
16= w or width
2) A=lw
A=7 x 12
A= 84
3) A= 12 x 21
A= 252
