I assume you're asking to find the coefficient of the
term in the expansion of
.
The binomial theorem says that the expansion itself is
and we obtain the
term when
. So the coefficient of this term would be
Answer:
Case (c) has the lowest unit price and is thus the best buy.
Step-by-step explanation:
Example: (a) The unit price is the price paid divided by the weight:
$0.50
------------ = $0.2857/oz, or (to 2 decimal places) $0.29/oz
1.75 oz
(b) $1.00/(6 ounces) = $0.17/oz
(c) $1.88/(12 ounces) = $0.16/oz
Case (c) has the lowest unit price and is thus the best buy.
Since each side of the cube is 3 inches, therefore:
Volume= Length x Width x Height
V= 3x3x3
V=27 inches
Therefore the volume of the box is 27 inches.
All you have to do is substitute the numbers in the variables so it would be
14/1-7+4(5)
=14-7+4(5)
But you have to do pemdas so you would start with multiplication so it would be
=14-7+20
=7+20
=27
