Answer:
Step-by-step explanation:
The number of people who receive the email after t weeks can be modeled by the following equation.
In which P(0) is the initial number of poeple who received the email and r is the factor.
Karim sent a chain email to 10 of his friends.
This means that 
The number of people who got the email increases by a factor of 1.4 every week.
This means that 
So
Which expression gives the number of people who got the email after 6 weeks?
We must remember the equation to find the area of a trapezoid first.
Area =
A and B are the bases (6 and 12)
The height is 6 for each trapezoid
Now Solve!
====================================================================
SOLVING...
Area =
Area =
Area = 9 * 6
Area = 54
Since there are two trapezoids, multiply 54 by 2
54 x 2 = 108
Area = 108
