Answer:
is proved for the sum of pth, qth and rth terms of an arithmetic progression are a, b,and c respectively.
Step-by-step explanation:
Given that the sum of pth, qth and rth terms of an arithmetic progression are a, b and c respectively.
First term of given arithmetic progression is A
and common difference is D
ie., and common difference=D
The nth term can be written as
pth term of given arithmetic progression is a
qth term of given arithmetic progression is b
and
rth term of given arithmetic progression is c
We have to prove that
Now to prove LHS=RHS
Now take LHS
ie.,
Therefore
ie.,
Hence proved
Answer:
Area = square units
Step-by-step explanation:
<u>Key skills needed: Area of a parallelogram</u>
1) This shape is a parallelogram, and the way to find the area of a parallelogram is:
A = area
b = base (the side at the bottom
h = the height ( the length that runs from one side to another and makes a right angle)
2) The base (b) would be 3x. The height (h) would also be 3x
3) This means A =
3 times 3 is 9 --> and x times x is
Therefore the area is -->
