Solution:
Given expression:
To solve this expression:
Apply the fraction rule:
Let us solve .
Least common multiple of is .
Make the denominator same based on the LCM.
So that multiply and divide the 2nd term by x, we get
Now, multiply by (x - 3).
Apply the fraction rule:
Cancel the common factor 36.
Hence the solution is .
Answer:
<h3>Greater than 20</h3>
Step-by-step explanation:
Since mean is the average number of students, the formula for calculating the mean attendance of students is expressed as;
Mean = total number of student/sample size
Given mean = 20
Since the question talks about the first four meetings, the sample size = 4
<em>Since the sum total of students for the first four meetings is 80, hence the number of students who attended the meeting is greater than 20</em>
slope = 13
the slope of the tangent is f'( 4)
given f(x) = x² + 5x , then f'(x) = 2x + 5
and f'(4) = ( 2 × 4 ) + 5 = 13
After 5 seconds, that is the answer.
