The area of a triangle with base
and height
is given by
. In the trapezoid, the two triangles share a height of 6, however one has a base of 6 and the other has a base of 8.
Area of smaller triangle (triangle on the left): 
Area of larger triangle (triangle on the right):

Write an equation in point-slope form of the line that passes through the point (−6, 6) and has a slope of m=3/2.
The original 15 people are 10% of the total number of people who received the mail.
Step-by-step explanation:
Given,
Number of people who received mail = 15
Mail further sent to 3 more friends;
