After she worked out the problem, she had a discrepancy (disagreement) of
about 45% between her estimate and the quotient.
That's a lot ! There's almost definitely a major mistake somewhere, and
there really isn't any way to tell whether the mistake is in the estimate or
in the quotient.
My answer to the question is that Lilly has to go all the way back to the
beginning, and do the whole thing again. Only this time, she has a harder
job to do: She not only has to make another estimate and work out the
division problem again. This time, she also has to find the mistake that
she made the first time ... and there may be more than one of them.
Answer:
48
Step-by-step explanation:
the number of shirts are 3, number of pants 4, number of socks pairs 2 and 2 pairs of shoes.
first lets start with shirts and pants, number of unique combinations are,
(for each shirt there are 4 different pant combinations) = 
=12
similiarly for each shirt pant pair there are 2 shoes and 2 socks pairs.
thus, total number of combinations are=
= 48
Just subsitute 8 for n
1/2(8)^2-1/2(8)
1/2(64)-4
32-4
28

Answer:
2y-4x
Step-by-step explanation:
(6x-2)(6x-2) = 36x-12x-12x+4 = 36x+4
