<u>Answer:</u>
are two roots of equation
<u>Solution:</u>
Need to solve given equation using quadratic formula.
General form of quadratic equation is
And quadratic formula for getting roots of quadratic equation is
In our case b = -1 , a = -3 and c = -3
Calculating roots of the equation we get
Since is equal to -35, which is less than zero, so given equation will not have real roots and have complex roots.

<span>windows on first floor = 52
</span>
<span>windows on 8th floor (52 - 6 * 7) = 10
</span>
<span>average windows = (52 + 10)/2 = 62/2 = 31
</span>
<span>8 floors * 31 average windows = 248.</span>
Answer:
32 days
Step-by-step explanation:
Assume that the jar is full initially, containing 24 oz. After how many withdrawals of 3/4 oz will the jar be empty?
24 - (3/4)n = 0, or
24 = (3/4)n, or 96 = 3n. Dividing both sides by 3, we get n = 32.
The jar will be empty after 32 days.
