Recall that a combinatorial proof for an identity proceeds as follows: 1. State a counting question. 2. Answer the question in two ways: (i) one answer must correspond to the left-hand side (LHS) of the identity (ii) the other answer must correspond to the right-hand side (RHS). 3. Conclude that the LHS is equal to the RHS. Using this proof method, give a combinatorial proof of the identity

from the figure we get,

the x axis shows   the months and,

the y-axis shows the number of satisfied customer.

each line or each cell in upward direction (y-axis) shows 500.

the appropriate scale for the y - axis is: -

a = 2000 customers

b = 4000 customers

c = 6000 customers

d = 8000 customers

e = 10000 customers

f = 12000 customers

g = 14000 customers

the answer is a if my teacher taught me correct

where is the diagram? shown below where? ?

step-by-step explanation:

multiplication is multiplication.   it might feel harder depending on what level of math you are in, but generally it will be the same old stuff, while implementing some new concepts and methods of solving work.
