Answer:
The area of rectangle ABCD is 
Step-by-step explanation:
Plot the figure to better understand the problem
we have the vertices
A(-4, -2), B(-2, -2), C(-2, 7), D(-4, 7)
see the attached figure
The area of the rectangle is equal to

where
L is the length
W is the width
In this problem we have
---> difference of the y-coordinates
---> difference of the x-coordinates
substitute

Answer:
<h2>6.5</h2>
Step-by-step explanation:
Given the sum of the series represented as
. <u>To get the sum to infinity of the geometric series, we need to get its first term and its common ratio</u>. comparing to the general term of the sum of series of a GP
a = first term of the series
r = common ratio
On comparing to the given series, a = 1.3 and r = 0.8
Sum to infinity of a Geometric series is expressed as:

Answer: 3
Step-by-step explanation:
Pretend A is just three, B is just 4, and C is just 5.
3(3)-4(4)+2(5)
9-4(4)+2(5)
9-16+2(5)
9-16+10
-7+10
