<span>Triple 4 and subtract 2 each day
Find the number of days to be able to reach zero
1st day = 3(4) – 2
=> 12 - 2
=> 10
2nd day
=> 10 - 2
=> 8
3rd day
=> 8 – 2
=> 6
4th day
=> 6 – 2
=> 4
5th day
=> 4 – 2
=> 2
6th day
=> 2 – 2
=0
In 6th day, you’ll be able to get the amount of zero by subtracting
3(4) by 2.</span>
Less than 2 = z < 2
Less than or equal to 8 = z ≤ 8
z ≤ 8
z < 2
X^2-13x+30
x^2-10x-3x+30
x(x-10)-3(x-10)
(x-3)(x-10)
so two zeors are 3 and 10 !!
X= 8 :)
I hope this is correct
