Use the process of elimination.
There is a positive b value and a negative c value, which means that there is a negative factor and positive factor. This eliminates A and C.
Multiply out the factors in B and D:
B
(6d - 1)(2d + 1)
6d * 2d = 12d^2
6d * 1 = 6d
2d * -1 = -2d
12d^2 + 4d - 1
D
(6d + 1)(2d - 1)
6d * 2d = 12d^2
6d * -1 = -6d
2d * 1 = 2d
12d^2 - 4d - 1
The answer is B.
The ratio of Mrs Lee's age to her son's age now is 4 : 1
5 years later, the ratio of Mrs Lee's age to her son's age will become 3 : 1
How old is Mrs Lee now?
Answer: Let Mrs Lee's age and her son's age now be 4x and x respectively.
Mrs Lee's age after 5 years = 4x + 5
Her son's age after years = x + 5
We know that the ratio of Mrs Lee's age to her son's age after 5 years will be 3:1. Therefore, we have:
![\frac{4x+5}{x+5} =\frac{3}{1}](https://tex.z-dn.net/?f=%5Cfrac%7B4x%2B5%7D%7Bx%2B5%7D%20%3D%5Cfrac%7B3%7D%7B1%7D)
![4x +5 =3x +15](https://tex.z-dn.net/?f=4x%20%2B5%20%3D3x%20%2B15%20)
![4x -3x = 15-5](https://tex.z-dn.net/?f=4x%20-3x%20%3D%2015-5)
![x=10](https://tex.z-dn.net/?f=x%3D10)
We have son's current age = 10 years
Therefore, Mrs Lee's is
years old now

Based on the diagram, the true statement is "If a student is an honor student, then he/she may also be a band member."
<h3>What does the diagram show?</h3>
It shows the intersection between two groups:
- Honor students
- Band members
This intersection implies some band members are honor students and vice versa. However, not all band members are honor students and not all honor students are band members.
<h3>What can be concluded?</h3>
A correct conclusion is that an honor student may also belong to the band.
