So our original equations would be..
(a) perimeter in terms of y
(b) area in terms of y
*I'm actually not sure about b.. sorry*
(c) if perimeter = 28, find length
Multiply the length*width*height to get the volume of the prism then, take out the difference between the volumes
Volume of the prism= 1018464
Then just subtract
Step-by-step explanation:
a rectangle has two pairs of equally long sides and each of the 4 angles between the sides is 90 degrees.
given that ABCDEF is a regular hexagon, it means that all its sides are equally long, and therefore also all internal angles are the same size.
that means for ACDF that the sides DC and FA are equally long.
DEF and ABC are congruent triangles, as the sides DE = BC, EF = AB, and the angle E is congruent to angle B.
based on the SAS criteria this confirms that DF is congruent to AC.
the angles ACB, CAB, EDF and EFD have to be all the same, and therefore also the angles FDC, DCA, CAF and DFA.
so, all 4 angles of the parallelogram ACDF are the same, and the sum of all these angles has to be 360 degrees, we have
360 = 4×angle
angle = 90 degree.
so, all angles are 90 degrees and we have two pairs of equally long sides : this process that ACDF us a rectangle

Answer:
The unit fraction is 1/3 and the whole number is 4 2/3 however its a mixed fraction so I'm not positive about it so you could make just use the 4 as a whole number.
Step-by-step explanation:
The unit fraction is written using a numerator of 1 and keeping the original denominator. So it would be 1/3. 3 goes into 14 4 times so you get the four there. however there is still 2/3 as 3 cannot go into 2. however if you would like to you can convert 2 divided by 3 into a decimal or 0.666666667.
