Answer:
306.
Step-by-step explanation:
Firstly, we are aware 100% of 680 is obviously 680,
Next, we know half of a 100% is 50% therefore half of 680 is 340.
Then, we know 45% is 5% less than 50%
To find 5% of a number mentally, divide it by 10 as 100÷5=20
680÷20=34
Lastly 50% subtracted by 5%: 340-34=306.
Now we know, 45% of 680 is 306.

Answer:
n² - 6n - 16
Step-by-step explanation:
As per the question,
We have been provided the equation
(n-8)(n+2)
To find the product, we have to multiply the both term,
(n - 8) (n + 2)
= n (n + 2) - 8 (n + 2)
= (n² + 2n) - (8n + 16)
= n² + 2n - 8n - 16n
= n² - 6n - 16
Hence, the required answer of the product of (n-8)(n+2) = n² - 6n - 16.
