<em />
<u>Solution:</u>
c means client meetings and o means other work.
The hours are shown in the table.
We want % of time on Thursday that he spent on clients.
In Thursday:
7c and 3o
Means 7 hours with clients and 3 hours with office work.
Total time spent = 7 + 3 = 10 hours
Client time spent = 7 hours
% time spent with clients on Thursday: 7/10 = 0.7 * 100 = <u>70%</u>
<u>Answer choice B is right.</u>
First, you need to set the equation equal to zero:
n^2 + 7n + 10 = 0
Now we factor. We need to find two numbers that add up to 7 and multiply to 10.
2 + 5 = 7
2 * 5 = 10
Now, we just need to write this as a polynomial:
(n + 2) (n + 5)
is our answer.
Hope this helps!
The answer is one thousand five hundred thirty eight
