For c to be positive, and for b to be negative, m must be negative and n must be negative.
X^2 - bx + c = (x - m)(x - n).
c is the product of m and n. If both m and n are positive, c would be positive. However b is the sum of m and n, therefore to make b negative, both m and n must be negative to ensure that the product of m and n is positive

Answer:</h3>
<h3>
Step-by-step explanation:</h3>
In this question, we're trying to find the amount of people that did not vote and the percentage of people that didn't vote.
We know that 65% of people voted and percents are out of 100%.
We would subtract 65 form 100 to get out percentage that didn't vote.
35% of people didn't vote.
Now, we can solve the next question.
A total of 75,000 people voted. What we're going to have to do is find how much of 75,000 is 65%.
We would do this by multiplying 75,000 by 0.65
This means that 48,750 people voted.

8 is the answer because you count up from the lower number
We use unitary method over here. To find out the number pages he writes in 1 hour we should;
16÷8 = 2.
So Brennan writes 2 pages in 1 hour.
Hence, in 10 hours he writes;
2 × 10 = 20.
∴ in ten hours Brennan writes 20 pages.
