12000 x 0.40 = 4800
12000 - 4800 = 7200
7200 acres are being logged
hope this helps
I don’t think you can solve by using quadratic equation
Answer: So, our required linear equation will be

Explanation:
Since we have given that
the number of fruit flies = 6
According to question, we have that the number of fruit flies in a population doubles everyday,
it becomes geometric progression, as it rises with common ratio, i.e.

Let the number of days be x
so, our required equation becomes ,

So, our required equation will be

32. The absolute value of a number x (|x|) will always be positive. It just means how far the number is from 0 on the number line.
Answer: Z²+ 9Z + 8
Step-by-step explanation:
You take the two z's and times them to get Z² then you do the Z times 1 to get 1Z then you do the Z times 8 to get 8Z then you take the 8 times 1 and get 8 so then you add the like terms. You add 1Z and 8Z and you get 9Z. The you put it in standard form to get Z²+9Z+8
