Answer:
c
Step-by-step explanation:
gm=cm+rg
gm-cm=rg
m(g-c)/g-c = rg/g-c
m=r g/g-c
-3m=4m-15
-3m-4m=-15
-7m=-15
-15/-7m
= -2.14
-15/-3-4= 2.14
Answer:
Trapezoid
Step-by-step explanation:
The points are shown in the attached graph.
<em>You can clearly see from the picture that it is a "Trapezoid".</em>
<em />
<em>Trapezoid</em><em> is basically a quadrilateral (4 sided-figure) that has 1/2 pair of parallel sides.</em>
<em>On the other hand, a </em><em>parallelogram</em><em> has 2 pair of parallel sides.</em>
<em />
Thus, a parallelogram is a special type of trapezoid where there are 2 pair of parallel sides. But trapezoid need not be a parallelogram.
<em>The picture shows 1 pair of parallel sides, hence it is a </em><em>trapezoid.</em>

Answer:
23.5 inches^2
Step-by-step explanation:
Area of triangle = 1/2 * base * height
area = 1/2 * (5+2) * (5+4)
area = 31.5 in^2
Area of rectangle = length * breadth
area = 4 * 2
area = 8 in^2
Area of figure = area of triangle - area of rectangle
area = 31.5 - 8
area =23.5 in^2
